I think I can answer the wheel question for you.
Depending on what shop y ou ordered from they get a "launch" package. This is the truck and a extra set of wheels for a certain price for the shops. The wheels/rims I think are just to help out the shops a little as a promo offer. If they choose to enter them into the shops inventory or give them to you with the purchase of the kit I think it's all up to them.
Where did you order one from? Just ask them what the plans are.
