Suggestions on the proper receiver for me

I am looking for suggestions on the proper receiver for my setup. I am working on my theater room now. I am going to be running Martin Logan motion 12's for my fronts with a motion C for the center channel and a Klipsch 12d for my sub. I'm not completely sure yet on what I will be running for the surrounds but it will be a 7.2 system. I am also planning on using a couple speakers in my pool table room that will have a wall mounted tv for anyone watching in there and want to be able to use those as a second zone (for when we might be watching a football game or something.) I will be running a Panasonic 8000u as my projector. My signal will be coming from a Dish Network HD box and a blue ray player and/or a pc. I was wondering if I am better going with something lower end on the receiver end and running an external amp to drive the speakers or what my other options would be. I would honestly like to keep the cost of the receiver under $750 or so. Thanks!

Is the 12v trigger so when you turn the receiver on it would power your projector? Any other advantages / disadvantages for not having a 12v trigger? I have really been leaning towards the sc-1222, especially since newegg has had it on sale. It seems like it would do all the things I need it to do. I am really wanting to hold out for the onkyo 818 to go back on sale but it doesn't look like that is happening anytime soon. Is it that much better overall then the ones listed above?
