I think your going to have a hard time getting guys in here to recommend in ceiling speakers for more than ambiance music listening and multiroom intercom duty.......
Some more info like room sizes would help, are you going built in subs too?
The speakers you are looking at are decent, but I wouldn't put the surround sound setups in the ceiling I would go in wall.... or if that doesn't work, just get a decent sound bar for under or over the tv and call it a day because in my experience no matter how much you spend on a speaker if you mount it 5 feet over your head and fire it straight down to the floor, you aren't going to get the greatest sound, and when you couple this with surround effects, it just makes a mess, and distracts the listener, its hard to disappear into the material when your attention is constantly getting pulled away and directed at the speaker making the noise.......
But for the most part you have nice speakers listed, IMO though you can go much cheaper since its already starting off on limped legs...
