I agree the pricing doesn't look too bad to me but I would go the Axiom route for the speakers, again I am not a fan of in ceiling ones as well.
I know for my second zone off the Denon 3808 I would need to run another amp as most in this price range appear to need one.
I do remember a number of years ago Sony had a receiver out that would do 3-4 seperate rooms with different input sources for each room but it was very pricey. I thought at that time it was cheaper just to use smaller individual receivers in each room.
