1. I use newspaper personally. IMO, newspaper/paper, paper towels, and aspen are the only three that should be used. They are easy, sanitary, and safe.
2. I don't use bulbs. They suck every last drop of humidity out of the tank, but I also use tubs. Tubs are much easier to maintain humidity and temp wise.
3. I get my thermostats from Reptile Basics. I personally wouldn't waste money on anything cheaper than a Rancho or a Johnson. I really love my Vivarium thermostats from RB, I also have a Rancho and Helix for back ups.
