The pet store told me to set it at 95-100... -headdesk- I'm going to just throw out everything I was recommended to do by the store.
The heat pad they sold me does not have a thermostat. The hide is a little big but the other one in the cold is too small. I supplemented the small one by adding the fake leaves around it and situating the log piece so it doesn't have an opening on the other side. He seems to prefer this colder one, but I figured he'd be able to regulate himself as needed...
Im going to be making another trip to the pet store today to pick up more hides and things to make the enclosure smaller for him, and see if I can find a humidifier.
