I have used exo-terra digital hydro/thermometers (take the humidity probe out until you need it) and nat geo digital hydro/thermometer (no probes, works well except mine corroded inside because I never took it out, so I'd only put it in long enough to get a reading and then take it back out.) I far prefer the cheap glass thermometers, but having planted tanks, I usually have a good idea on the humidity levels by the appearance of the plants and the smell of the tank.
I personally wouldn't keep the hot light over the water dish because the water dish is where she'll go to escape the heat.
If the humidity is a little low, you can cover part of the screen top with glad press and seal, it works pretty well for a temp set up. I wouldn't worry about the planter on top of the tank, it's not going to block enough air flow to affect her.
You're going to need a BIG tank for all those froggies!
