Well I'll start off with just a couple things. Everyone on here says you should leave them alone for a week so they can get used to their surroundings.
Second this varies slightly but the general consensus is 90-93 hot side 80-82 cool side.
Third if you have different hides (as opposed to identical ones) he may choose between hides instead of the temperature he needs.
Last (for now) you don't need to worry about him grabbing on to you at all sometimes he may just be content to chill in your hands.
Hope that helps
