How to care for a 6 week old Netherland Dwarf Bunny?

Ok, so I bought a 6 week Old Netherland Dwarf Male and it is super young! the lady told me it was Ok to go home because since their size is so small, they stop drinking milk from their mom early. So they bunny is in good conditions, playful. This is how I setup his cage. I put 2" inches of aspen bedding, 1 water bottle, toys, Hay rack, timothy hay, food( alfafa pellets). The bunny eats aspen bedding too? is that ok? I havent seen him bite the pellets since I put him in the cage but he has been eating hay, and some grass? What else should I know? Is he going to eat later when he gets super hungry? please help!!
