Sounds like you have it together. Standard dogma says that the hot side should be in the low 90s, and a cool end in the high 70s, with an ambient in the high 70s/low 80s. Set your thermostat and try to get close, but don't worry if you aren't spot on. Usually a large water bowl with limited tank ventilation will give enough humidity. If you aren't around 50-60%, think about providing a humid hide. Damp sphagnum moss in a tupperware with a hole cut in it works great.
