It's been a few years since I've done a lot of reading up on Home AV setups, however the best place there is to read up on it is AVS Forums.

It is, without a doubt, the best place on the net for the information you're going to be looking for. I'd suggest doing a bunch of reading on the forums there. If you can't find the information easily just post something, there's a tonne of knowledgeable people on there.
