Need help with home theater components

First post here. I'm building a new house and setting up a home theater at the same time. I am pretty confused. I need to figure out which components I should buy (receiver, dvd/blue ray, ?)

Here is what I am having installed:

5.1 in-wall speakers:
Proficient Audio C870 ceiling mount speakers
Proficient Audio IW550 center channel
Proficient Audio S10 Subwoofer
Television will be a 1080p 50"-60" LCD or DLP (not sure yet)
It is not a theater room but a section of a very large rec room.

I also have a Nuvo 4 zone controller for whole house audio. I think the only way the receiver comes into play here would be as the AM/FM radio.

Where I get very confused is which receiver I need. I get confused with the 1080 switching, passthrough, etc.? I am spending several thousand dollars on the above mentioned setup, so I so want nice quality video and audio but I am not a die hard audio or videophile like some people. In other words, if spending $500 extra on something that only the keenest of ears or eyes would notice then it's not worth it. I do, however want to take advantage of a new HD TV and have an impressive home theater. I also want to future proof myself to some extent. Now that you have a better idea of where I'm coming from here is what I'm considering.

Receiver - leaning towards Onkyo or Yamaha based on advice, reviews, etc. thinking I need to spend $500-900 ish????????

DVD/CD - Thinking about Sony DVP-NC85H/B HDMI/CD Progressive Scan 5-Disc DVD Changer for use as my DVD player as well as CD player for whole house audio??????

Blue Ray - Will probably wait it out and maybe get one down the road unless you convice me that I need one now.

IPOD/MP3 - Do I need a $100 docking station or just a $10 cable that connects it to the receiver?????

Any advice would be appreciated. Thank you very much in advance for your time. I would also consider buying equipment from sources on this board.

Thank you,
Mike

Thank you both very much for the informative responses. That helps a lot with making my decisions. Any other advice/experiences from others would still be very appreciated.

Thanks,
Mike

Glad to hear you like the Proficient Audio speakers. They are actually being installed next week so I have yet to hear them. I bought the Onkyo 605. I debated a long time about the 605 vs the 805. Hopefully I won't regret it. Are your Proficient speakers for whole house audio or home theater (or both)? If they are for your theater what TV do you have. That is my next step, I'm leaning towards a 60-65" DLP. Thanks again!

The speakers were just installed but I am not moving in for about a month. Since it is new construction, I won't set up the controller, receiver, and tv until the house is totally finished and I move in. I will try and update with my thoughts and maybe even pictures when I move in. Thanks!
