For this type of system, I am going to commit herasey on this board, and say the Definitive Technology Ceiling speakers are great. So are the Niles HD ceiling speakers. The Def Tech 63 or 84's are a great choice, and put out a surprising amount of bass without building resonance boxes around them. I have helped a couple of friends build systems almost exactly as you describe yours with these speakers and usually a Denon 2808 (or similar) reciever. Very nice set up.
If you add the Def Tech sub, the sound matches extremely well. Also, for the center channel, a couple of times we have omitted the center channel all together, and programmed the processor to put the center channel sound through the Front R & L speakers. Simple, but very nice set up. good luck.
