I know it's a lot to take in all at once but trust me, it all gets easier- especially if you hang around here some. It sounds like you're on the right track, & you're obviously a good "listener".
BTW- the "humid hide" should be on the cool side, or midway at most. It would dry out too fast on the warm side, & besides, when snakes goes into "shed", they generally prefer the cool side & that's when they most need a humid hide.
