Naruto and Obito never left the ground. Naruto was no longer holding the TBB with his own body, the weight was no longer on him. Also, Naruto literally couldbt put his foot down by the time Obito reached him.

The TBB doesnt seem to have its negative effects since he and Kurama became buddy buddy. He is able to form it, hold it, and leap through the air with it perfectly fine.

Shunshin is ninjitsu. It doesnt have to be elemental in order for Rinnegan to boost it.
