Thanks for the input...I'll address your points/comments/suggestions:
Size of the room: It's a fairly open space. About a 1200 foot condo, and this will go in the main room, which is an open layout along with the kitchen.
I plan on getting the sub that comes with the package. It'll go on the floor to the left of everything. Close to the corner near the window. Not up against the window, though. About 2-3 feet away.
Thanks for your advice on the speaker wire. I would never get Monster on principal alone. As for the HDMI's my first HDMI cable is a Belkin. I'll probably stick with those. I looked on Amazon and they're pretty reasonable. Need maybe 6 feet.
YPAO thingy? Please explain to this novice! I know the receiver will calibrate the speakers. Is this what you're referring to?
As far as placement of the speakers, I think I may just leave the Bose in the wall and just not use them. (Decided not to mess with patching the wall, etc.) I'll probably get stands for the Klipsch left and rights and place them as far as I can away from each other. The TV is in a built-in resting on a marble slab, so I'll just put the center on there in front of the TV.
The rears will also go on stands at the far end of the room. The calibration will recognize that they're back there, correct?
Another question...What is the difference between the Quintet package and the HD 300 package that they're advertising on the website?

If they're comparable, or if the 300 package is better, perhaps I'll have some pricing leverage.
Thanks again!!
