get a boombox on a nice table
and a cd rack next to it.
and for your cable problem. what you do is make sure all the wires follow the wall where they can. then put a little box over them. color the box the same color as the wall, and then fasten it to the wall (nails, staples, gl00, you get the picture) just make sure you can take it back off to add moar cables, as im sure your going to be adding a lot more to your room.
