A ZM heatpad with the rheostat will work fine if your room stays at a good strady temperature of around 75-80. I actually use these heatpads in my rack, and they have always served me well. They do get too hot without the rheostat though!
Sorry, I just saw that you switched to the tub Tubs hold in humidity pretty well; sometimes, too well. I would cover some of the holes you drilled in with plastic wrap (taped to the outside of the tub so that the snake can't get to the tape if it were to stick its tongue through the hole somehow.)
