I have never worn gloves. I really think it's up to you, if it makes you feel more comfortable, I don't see a problem with it.

As for the humidity issue, mine is usually around 60-65 and I haven't had any problems. 70 sounds a little high though.

A suggestion for you: You should have 2 secure, enclosed hides available for your snake, one on the cool side, and one on the warm side. Your snake will greatly appreciate it and be less stressed. I'm not sure what the reptile gym is without seeing a picture, but if it provides a nice hide for your snake, fine!

A question for you: What are you using to monitor your temperature and humidity? If you don't have one already, I would get a digital thermometer/hygrometer from Walmart. They are accuruate and can measure both sides of the tank (which should be ~80 on the cool side and ~90 on the warm side) AND it measures the humidity, all in one!

About feeding: You should try either fresh killed or frozen thawed mice. I would not suggest feeding live. The transition varies for each snake, he might take a f/t or p/k mouse readily. Or there may be more work/tricks involved such as doing the "mousie dance" to make it look alive.

Welcome, and continue to ask questions. We'll help you out the best you can.
