You have a lot of reading to do on this site.
I would not put anything sticky in the cage. A lot of us use the digital Accurite temp/humidity you can get a Wal Mart for $12. And you do not need the shed aid stuff or to bath him while in shed. Just keep the humidity up. If the shed goes poorly, there are several posts on here as to what to do next. The bath can actually make the shed go poorly as you was away the layer of oils that help the old skin come off, and IMO the shed aid is a waste of money.
You do not need 2 water dishes, but you do need 2 identical hides, one on the warm side and one on the warmer side.
Please describe the rest of your set-up in detail (size, layout, temps, humidity). Are you using a heat pad on a thermostat? Which thermostat?
In the mean time, get to reading the stickies in the husbandry forum, and good luck!
