I think the prioritization of equipment is required here. Mulch substrate,not required you can use paper towel. Special hide. Not required, I use left over food containers. Special water bowl. Not required. Go to the dollar store.
What is required is that you lose the human heating pad. Those things are not reliable. I fell asleep on one and burnt the crap out of myself. You need a reptile mat or heat tape. THese things should be regulated, preferably with a thermostat. The way you are set up now it is not a matter of if there is going to be an accident, it is a matter of when.
