RE: How should I fill my new play room?
I think something like this from Ikea is perfect for organizing toys. http://tinyurl.com/4tuoa They have baskets that fit very nicely into the shelves for a Pottery Barn look.
I would make a little lounge area with lots of pillows, bean bag chairs, or soft chairs and a nice rug. You may want to put a tv with a DVD player in there if you allow your DS to watch movies.
Also a table and chairs set or a train table would be really nice. My DS has the Little Tikes Basketball hoop and he loves that as well.
