What kind of bedding should I use??

Was using paper towels. Switched to kraft indented paper because it's wider and a little easier to work with. Both were easy to spot messes and it's easy to replace the paper.

I live in FL, so humidity isn't an issue for me. If you live in a dry area or your house is particularly dry, humidity may be a concern.

I use Eco-Earth. Nice and soft, Loki loves to burrow in it sometimes. Also great for humidity!

I also use indented craft paper from ULINE.I order a couple rolls at at time so save on shipping. Its easy to clean and it's really easy to get the hot spot temps perfect with paper. I have used shredded aspen before and had to raise the temps on my thermostat to about 97 to get a 90 degree hot spot. With paper the snake is closer to the bottom surface of the tub so there is less bedding to heat to reach the snake ( my racks are not in a heated room ). Only pain with a roll of paper is having to cut them to size, its not difficult just a little time consuming I usually cut 10 -15 sheets at a time.
