He still has everything from the war except his TSB. The TSB have been destroyed in the war and in his battle with Sasuke, and he can't reproduce others.

The yellow chakra cloak is just Kurama's cloak and has nothing to do with six paths sage mode. Naruto combined Kurama's chakra mode with SM to obtain KSM (what he uses when he battled Obito and Toneri) and combined Kurama's chakra with SPSM to obtain what he used against Madara/Kaguya/Sasuke/Momoshiki.
