Sounds like things are going well.
If it turns out you have mites check out Reptile Spray. It works great and you can get it at Petco.
Your humidity does not need to stay so high. You can get great sheds with it within the range of 40-60%. My tank stays at 30% and with moss in the hides I get perfect sheds. While low humidity can create issues, so can high humidity. You just need a good balance.
