Baby Boy's Room!

I have been working sooooo hard all week nesting. I know it is a little early but I've been going at it for a while now. I guess I want to be on top of things before the kids get out of school and before I get too fat. We have a lot going on this summer and I want to be able to lay by the pool and work on my tan when we are around instead of organizing my house. Anyways, I have been painting my butt off this week. John helped me with the nursery ceiling last weekend (it was yellow, now it's white) and since then, I've done the walls, sanded and painted the dresser and knobs, the blue slats on the bed and the crib. If I never see another piece of sandpaper it will be too soon! So we got the room set up and now I don't know where to go from here. It is way too matchy matchy. I love the crib bedding (click on the picture and you will be able to see it better) but I need to bring in more to the room. I especially need advice for what color to put on the twin size bed ... should I get a tan duvet cover? I have ordered a yard of the brown and white houndstooth fabric (like the ties on the bumper) to maybe make a sham or something. I also need a lamp and maybe some sort of window treatment. Somebody help me???
