I would say paper towel is the best substrate. It's so easy to clean, and in all honesty it doesn't look that bad, just white. If you want something more naturalistic you could go for reptile carpet, but some people have said their gecko's teeth got stuck on it. I wouldn't recomend sand, of any type; calcium carbonate, or play sand. It can cause impactions. Two hides are good, you'll want a humid hide too, this can be your warm hide. It is easiest to cut a hole in a tupperware container, then fill it with paper towel or soil. I tried using soil and my geckos kicked it all over the tank. So basically you keep the paper towel or soil moist in that hide and it helps them shed and what have you. Your warm side should have a temp of about 90F and your cool side 75-80F (i believe)
anyway hope this helps
