Also is there a cheaper way to get Repti-Carpet? And could someone tell me the best kind of bedding? I know aspen is commonly used, is that shavings?

So I need a thermostat to control the temps and that's connected to the UTH. Does the t-stat come with two probes one for the cold and one for the warm side? Do I need a thermometer to double check those temps? The one I have only has one probe.

Once I have the belly temps correct, does the ambient temp sometimes take care of itself? Or will I most likely need a CHE also?

I'm looking for the cheapest options to save money, but if something necessary is going to be expensive not matter what that's fine, of course.
