Having just gone through your exact situation, I feel at least somewhat qualified to give my opinion. I found lsf to be very useful. If you are like me (just in my forties) then you probably have some ancient experience with the DOS command line. I would strongly recommend going cold turkey and not using the GUI in whichever distro you choose as your learning environment. I also strongly recommend a subscription to the O'reilly safari bookshelf and the following three books: the infamous 'cowboy' book, "running linux" and the pocket guide of same, and the "essential system administration' pocket reference.
I fouund the sys admin ref book to be especially useful because of it's task based format. This is stuff that we do on a daily basis with a straightforward way of doing it.
Anyway, just my two cents. Best of luck to you.
