Nagato shouldn't be able to use any other than the basic Rinnegan abilities since they aren't his eyes. Certain techniques may also ne specific to each person. Kabuto gave him the order to fight but I dont believe he was pulling the strings move for move.

What makes you believe the 6 Paths Sage upgrades were temporary? Naruto still had the 6 Paths Sage Mode after Hagoromo left.
