Hello, welcome to the forum and the wonderful world of snake keeping!!
1) 94 is too hot. 88-89 is ideal. Also, the probe goes OUTSIDE the enclosure sandwiched between the UTH and the glass. When inside it can and will be moved, laid on, peed on, etc...which can all cause inaccurate readings and potential heat spikes, which can severely burn a snake or even be fatal.
2) it sounds like that light is fine. It's probably not too different from natural moonlight.
3) without seeing the scales, it's hard to say.
One thing I will say is that I strongly advise new keepers to hold off on handling new snakes until they've eaten three consecutive meals without refusal. Handling can equal stress, stress = refusals. The more important thing now is letting the snake settle in. You'll have 25+ years to handle your snake, let it get settled in And eating, that should be top priority.
