You could definitely move the current Accurite to the rack. I like my IR gun as another backup so I can check the temps across all the tubs and know where the flexwatt hot spots are (not always totally consistent down the length of the tape). It sounds like you're pretty set. I'm guessing you already have a spray bottle for misting. You can pick up cheap bowls and hides (if you plan to use them) as you come across them, but there isn't a huge need until you are expecting to add snakes to use them. Oh - I would set up the rack in a room other than the one you have your current BP in. This way, you can use it for QT when you add others, and then move her into it once their QT time is up (if this is feasible for how quickly you are going to have additions).
