It sounds like you have your bases covered. It isn't necessary to boost the cage temps as the cage should have a gradient from the low 80s to low 90s all the time, but it's a good idea to boost the humidity or provide a humid hide. Soaking is not necessary unless your snake has a bad shed.

Other than that, just leave him alone and let him do his thing. He'll spend most, if not all of his time in his hide until he's finished.

Good luck!
