Noob needs guidence with surround sound bars regarding my setup

So i searched around for a little bit and noticed that it seems that most like the YSP line by Yamaha when it comes to sound bars. I didn't find anything pertaining to my questions, so I'm posting this up to see if you guys can give me some pointers. I'm using this theater room for movies and gaming.

First my setup.

Samsung 46" LNT4665F (on the way from frys, only $1799 )
Xbox 360 Elite
Hd-DVD Addon on for Xbox 360
Playstation 3
Nintendo Wii
Gaming PC(7800Gt and native digital out for audio)
Logitech Harmony 550 Remote Control(on xmas list, stupid ps3 with no IR port)

Second the environment.

Basement with drywall wall and wood flooring.
13' x 12'(pretty much square)

3rd Budget.
I want to stay in the ball park of $600 - $1000 total for my complete audio setup. This is a small room, so I don't think I will need to much power, nor would I want it as this is a town home. If it is just north of $1000 that is ok(especially if I need a receiver). Looking for the best bang for the buck without getting into running cables on a traditional surround setup.


Questions???

1. I want to stick with a sound bar setup. What do you recommend given that I want all of these components played through the soundbar?
2. Would I need a receiver to connect all of the game systems as well? What do you recommend?

Thankya much.

Thanks for the info. I checked out amazon and noticed that they have the YSP-1100bl.

Is there any difference between the YSP-1100 and the YSP-1100BL's?
Where is a good place to pick up a YSP-1100 for cheap?
If I can't find one, is there any other option that is shy of the YSP-1100BL price of $1300(amazon.com)?
With the YSP-1100 do you still recommend a sub?

Thanks
