T.,
I am in a similiar situation, but I only tell you what worked for me, and is actually still working well! I have become a big fan of plastic storage boxes. At meijer they have these huge plastic colorful boxes with lids (red, yellow, blue, light green and beige), they are made in the U.S.A. They used to cost $10, but now cost about $13 unless you have a coupon. When my sons were younger I purchased two and only put one out in the family room at a time. I placed mine in front of the fireplace since I didn't like my boys playing with the fireplace doors. I filled both boxes with toys and put the other in my son's closet. Every two weeks I would change the boxes. My son would then really enjoy his toys because he hadn't seen them in two weeks, which was especially nice during the winter when the days can be long! As my boys have gotten older I have used these boxes to store their baby toys in the basement and still have one in front of the fireplace. My oldest is now 6 and if you were to open up his closet you would see a stack of smaller plastic boxes all labeled. When he wants his hot wheels out he just asks me to grab the box out of the closet. It keeps everything organized for us and out of the way. Hope that helps!
