Me personally I would unplug your UTH until you have thermostat to regulate it, the snake has a higher chance of being harmed with it plugged in unregulated.
You want to get your ball two identical hides, one for the cool and one for the warm side. I personally use these http://www.reptilebasics.com/hide-boxes
As for as feeding, I would also pick up a kitchen scale, you want to feed you ball 10%-15% of you balls weight. This is the scale I use to weigh my ball and its food. http://www.amazon.com/gp/product/B00...ls_o05_s00_i00
