He, he, he. . . I love that
I also bought 12G wires, banana plugs and HDMI cables, and I will finish setting it up tonight (I hope).
In response to your questions:
1) If you post the diagram, I will take a look at it.
2) Speaker stands: Lovan Affiniti 29" - $95 w/free shipping on Amazon.com
-I looked for 2 weeks on the net for the perfect stands and there is nothing else better for the price. Solid and sturdy, the 29" height sets the speakers at perfect ear level, and it has large top plates that hold the front Onkyo speakers perfectly. There are cheaper stands, but trust me on this, you get what you pay for. One thing I do recommend is that you get industrial strength velcro to secure the speakers - I did this, and now, the speakers stay on the stand even if I turn it sideways. BTW, Amazon has the best deal on these (yes, I looked).
3) As long as you don't plan to use the TV speakers, it shouldn't cause you any problems. But there are stands made specifically for the center speaker. You may want to check those out and you can have a much cleaner look to your system.

Here is a crude floor plan of my home theater space along with some pics for reference. The couch and tv can be moved anywhere in the room to accommodate the setup. The open space behind the couch is a window. Also, there is about 2 or so feet of wall above both entrances to the room and the window that can accommodate speakers if need be. Let me know what you guys think. Again, all help is greatly appreciated!
