You dont need a heat pad - beardies dont need belly heat, in fact it can burn them. If your room drops below 60 or so at night then you can use a ceramic heat emitter to keep the temps up above 60-65. ONLY use a CHE - never a red or black light bulb.
I would go with a 10inch heat lamp...as for bulb wattage, that depends...i would buy a box of 60watt bulbs, 75watt, and 100watt (they are REALLY cheap at walmart) and play around with them till you find the right combo.
Thermometers need to be the digital variety with a probe. You can buy these at the petstore, or walmart or home depot. They run 5-10$. Only digital thermometers are reliable.
You will also need a pure calcium carbonate supplement (no vitamins or d3 or phosphorous), and a multivitamin supplement with D3.
You will also need a tank to keep the crickets in for gutloading.
