I'm no expert...
It was recommended to me to keep my baby panther cham at about 82F-83F.
A regular 40 watts incandescent house bulb can produce this. Glass terrariums retain heat more than screen terrariums, so make sure you have a digital thermometer with a probe you can move around the enclosure to make sure you are maintaining proper temperatures throughout. You want to achieve a temperature gradient of 82-83F in his basking spot, down to the lower 70's in the bottom of his cage.
You'll also need a UVB bulb. The best would be to get a Reptisun/Reptiglo 5.0 flourescent tube.
