Receiver: Denon AVR-1507
Screen: TBD, thinking somewhere around 100"
Speakers: Have 1 7604 thus far to use as center, thinking of ordering 4/6 more (see below)
Room was prewired for 5.1 but I believe this receiver allows for 7.1 Need to read up and see if it would be worth running the extra speaker wire for the 2 additional channels.
The general concensus on the forums seems to be that the benefits of 7.1 over 5.1 are rather marginal - many "experts" seem to suggest spending more on upgrading 5.1 speakers over adding rear channels. There is a vocal minority, however, who do love the 7.1. I don't really have an opinion one way or the other since I've never had a 7.1 setup.

The usual advice is to place the LCR at about ear level if possible, so the answer to your question is probably yes.

That sounds just fine for the surrounds .... the usual advice is that they be placed a bit above ear level (say, 2 to 3 feet) and just behind the listener position ... they may be a foot or two high over optimum there, but I wouldn't worry about it at all.

Most of the experts seem to recommend in-wall over in-ceiling, so if you go 7.1, I'd probably stick with an in-wall installation and use the 7604s. Personally, I don't think it matters that much though, especially for rears, and if for cosmetic reasons you wanted to do an in-ceiling installation, either of the in-ceilings should be fine. I have a pair of the 4929s installed in my kitchen ceiling for 2.0 music, and I think the angled woofer would work well for rears, pointed toward the listening position.

Why not? If you don't like the way it sounds, then you can just upgrade whenever you want.

I'm not an expert, so take my advice with that in mind, but I have read quite a bit on the forums over the past 6 months, and I'm not bad at regurgitating what I've read.
