Need suggestions for speakers, processor and amp

I am building a new house with a 17.5 x 20 ft family room that will have a cabinet built to house a rear projection tv and will have cabinets/bookshelves built on each side to house speakers and processor and amp. Cabinet will be on the 17.5 ft wall and left side of 20 ft wall will have fireplace while right side will have approx 15 ft of windows. Ceiling height is 10 ft and rear speakers will need to be in ceiling. Cabinet can be built to house either bookshelves or floor-standers. My wife prefers front speakers built in to cabinet, although I may be able to place floorstanders outside the cabinet on each side. I am also going to buy a subwoofer. I'm considering totems or spendor (local av retailer recommends jamo concert series)

I also need suggestions for preamp/processor and amp. I don't know whether to go 5.1 or 7.1 in this size of room (rear centers would also need to be in ceiling). I'm considering the new outlaw 950 and matching amp, but I've heard good things about rotel.

Any suggestions would be helpful.
thanks,
mark
