Here is a really bad picture of my set up (sorry it's all I have right now xD).

You need two hides, one on the hot, one on the cold, without two it will not be able to thermoregulate properly.
Cover 3 sides of the tank, to make it feel more secure, and if you can, clutter that tank up! the more "stuff" the better. They like crowded, especially as babies.
I use eco earth, but repti bark should be okay if you mist every day, they need high humidity, you should also cover at least half of that screen top with tin foil, plexiglass, or a tamp towel to help keep the humidity in.
Also they are not a fan of white light, if you could replace the white heat bulb with a red night bulb or a CHE it will be much happier. That UTH should be regulated as well, you don't need a new one, you can buy a separate thermometer.
