A UTH is an under tank heater you can get them at the pet store or online I use www.reptilebasics.com. And you will need a thermostat to control the heat so your snake doesn't get burned.
The heat lamp can make keeping the humidity at the right level a problem.
I would also ditch the kleenex box and get a hide similar to the one you already have.
