We usually have a Meet the Teacher time the day before school starts, so I ask the kids to bring their supplies when they come in the letter I send them before school starts. Then I have a little sheet on their desk that has directions on where to put things. There are labeled containers on my reading table to show where each supply goes. It works out well, because the parents can help the kids and I am mostly free to walk around and meet kids and parents.
When everyone has left I begin the arduous task of putting the supplies away. Then when school starts there aren't a lot of things laying around. I leave the empty containers out for the kids who either didn't come to meet me, or those who didn't bring their supplies.
Hope this helps!
