sounds like you got most of what you need. Set up the hot side with the uth and put it at 90-94 USE a thermostat with the uth repti therm is the cheap option then you have johnson or ranco which are good or you can go all out on a herpstat or helix (herpstat recommended) or at least a dimmer with the uth or you will burn your buddy. As far as the light goes if you need it to provide overall temps in the cage then put it on a dimmer so that the surface of the substrate will be 80-84 just know that light will suck your humidity out.
