Your temps are a tad off. 82-84 cool side, 92-94 warm side. Your humidity is perfect.. should be between 50-60% most of the time, with 70% during shed times.

In my opinion, the human heat pads are just too irregular. Get in touch with Matt (justcage) and see what his advice is for a 75g tank. http://www.mgreptiles.com

Other than that, all seems okay.
