Help me buy a TV and suround sound for my bedroom

[TeeJayOrTJ]

I just moved into a new apartment and I am upgrading my room. I have a rather large bedroom at 21' x 11'. I think I am leaning towards a 42'' plasma, but not sure what to buy. I also need surround sound as well as a DVD player and perhaps a TV type stand to hold all the components. My limit for this purchase would be around 4K for everything.

Here is my room

ONe thing missing is the bathroom door which is next to the closet.

I dont think I want to wallmount the TV. I dont know how long I will live here. Although it is tempting. I could also put my TV on the dresser and have something next to it for recievers and cable boxes and Xbox360 and such.
