I would suggest putting lots of extra cabling in the walls. Even if you are not using the cabling it is much easier have it already in the wall instead of trying to run it again after the walls are already up. That means putting extra speaker/telephone/ethernet cabling everywhere, you never know what or where you might want to put something.
If you are worried about using wireless within the house and are not concered with using it outside you could look into using this paint as your base coat to protect the signal from leaking outside. Then you don't have to worrry about someone cracking into your network.
