It is to store the power: currently, there are no batteries capable of doing that. A major problem with the power generated from solar panels and any kind of turbine (wind, for example) is that it will be lost if you don't use it on the same turn.
I am not sure if that's what you asked, because your point may also be "why they are burning the natural gas to run this power storage facility, since power is already stored in the gas and they can burn it when they need it". In that case, it could be a matter of money: the gas is available now, and it is cheap. So maybe they want to store that energy as fast and cheap as possible, and sell it as pricey as possible later. I don't know.
the heavier deuterium will wind up sinking into the part of the cloud that becomes part of the star
Though deriving from simple principles, it is not that simple- accretion happens in at least two distinct spatial scales: the loose, yet gravitationally bound 'cloud' (called an 'envelope') is feeding the accretion disk. This envelope's size is of the order of ten or twenty thousand Astronomical Units (1 AU = distance from Earth to Sun), and takes forever to 'collapse'; the accretion disk, in turn, is feeding the central object, is much denser, and things happen faster. Typical sizes for the accretion disk are a hundred or a thousand times smaller than the envelope (few tens to a couple of hundred AU).
How exactly all this happens is an active area of research. One of the things that give some insight on the stellar and planetary formation process is measuring relative isotopic ratios on things in space, and comparing them to terrestrial and Solar values. What Conel Alexander and company here have noticed here is that the D/H ratio of Earth's water is more similar to the one of some Carbonaceous Chondritic meteoritic material than it is to some comets.
The Carbonaceous Chondrites are dated to be old. Not the first solids of the Solar System, but still among the first. They were also deemed to never have been parts of a larger body: they were never, say, part of an ancient planet, and then broke-off: they formed as rocks (condencing out of gas and dust) somewhere and at some time in the accretion disk, early. Or so the story goes.
I guess a ranting point can be that there is this theory of the Late Heavy Bombarment: there are people in the community that believe the Late Heavy Bombardment was also the origin of Earth's and Mars' water oceans, that came from comets (which carry lots of water). But water in comets, as it is now, is different than the water of Earth's oceans in terms of its D/H ratio.

As he puts it, they are "nothing more than glorified lab managers"- his type, I guess, since he is not running any classified military errands. A crew of three working in shifts around the clock is needed to maintain the ISS ("glorified janitors"), and that leaves room for three more people for extra tasks. Typically, when no tourist visitors are present, the remaining three of the crew work on a 'regular' 8-hour shift, formally complete with days off (e.g. during weekends). Tasks mostly include running experiments on board for third parties and, in theory, once their shift is over they can retire.
In practice, though, they do not get much free time since they do tend to feel a bit extra responsible for work, dedicating more time than it is asked for them to the experiments. Also, nobody on board misses an opportunity to get more hands-on experience on the interworkings of the ISS itself, since that can prove life-saving in case of an emergency. On top of that of course they need to excersize and, according to the one I met, the Russians are the best on maintaining their excersize routines, sometimes 3+ hours a day (also the smokers!)- other nationalities seem to not be prioritizing their work-out time much.
...just introspect a bit for your answer: put a pricetag on the utilities you are consuming and the systems that keep you safe and sound, and weight them against mankind's benifit from your research.
Then, do the same for the rest of the humans, and for your family, if you have any- it shouldn't be hard because apparently everything is taggable with a price, using your methods.
In that way, you can get a pricetag for everybody's life, do more statistics, and find your answer there somewhere.

One problem is: How will it tell apart a serious accident in which people were hurt
I guess, to a first approximation, by using accelerometer data: e.g. a simple spike would be a crash, a large spike would unfortunately be a harsher crash, a large spike followed by several smaller ones would be crash followed by tumbling, and no initial spike but several relatively small ones would be perhaps slipping off-track and tumbling.
"We believe that adults subsist for two to three weeks on the last feedings they had as juveniles and then die, hopefully (emph. mine) after they have reproduced,"
Yes, because more parasites is exactly what we need now.
Life, as we know it, does NOT prefer its Carbon in methane form, and its Hydrogen and Nitrogen in ammonia and hydrazine form. It also doesn't appreciate being baked in a superheated high-pressure poison soup.
Water, which is the ONE thing life-as-we-know-it needs, is still "in trouble" in Jupiter.
Energy? Yes. The Sun has lots of it, but I don't see any monkeys on it. Reason? It is too much, as it might be on Jupiter. Also no bananas.
Anyway, the key to energy is not only to get the right amount, but in the right way. The Jovian moons, for example, may be receiving energy from Jupiter in a proper enough fashion for "life as we know it" to function.
Overall, could there be DNA-ed bacteria and worms swimming about near the "surface" of Jupiter? Of course they could, anything "could". Are they high-priority for a billion-dollar mission? Of course not.

Early in the solar system's evolution after the sun ignited but before the planets formed
That's not necessarily true: last time I checked, whether tha Sun ignited before planets 'formed' is still an open question-- one that also affects the 'iceline' notion.

No, helium rain does not operate in a cycle of rain and evaporation. The He takes a one way trip deeper into the planet depleting the outer atmosphere of He.
You could be right- but it depends on who you ask!
How sure are you of this? As far as I know, methane (CH4) is a so called "non-equillibrium" gas (in the context of looking for haitable planets and such)
In english, that means that CH4 will quickly be destroyed (photodissociated)- so in order for it to exist for prolonged amounts of time, it will also have to be created somehow (i.e. "sources" of CH4)
Scientific teams use this to determine weather planets can (may) host life.
We could cryogenically freeze the astronauts and send them up as popsicles. Then, once we invent equipment to defreeze them, we can send that up and thaw them out. Problem solved. With enough creativity, nearly anything is possible.
The company surveyed the state of privacy laws around the world and found that the top three choices were Switzerland, Iceland, and Canada, so they went for the one within driving distance.
Going for the pro-citizen countries, are we? Switzerland has also recently allowed external investigators into its banks (as an example of on-demand privacy violations). I am not judgind it, I am only saying that it happened. So that's why the option that includes the servers sitting on a volcano and being surrounded by the ocean seems like a good choice.

Actually, some have been parts of larger bodies: it is these ones that haven't, but these are not mentioned in TFA or the publication.
What is the advantage?
It is to store the power: currently, there are no batteries capable of doing that. A major problem with the power generated from solar panels and any kind of turbine (wind, for example) is that it will be lost if you don't use it on the same turn.
