Don't worry about the questions. It's better to ask too many then not enough. I have that tank and I use a 100W ZooMed bulb for the day and a 75W ZooMed bulb for the night (at least in the winter, I use a little lower wattage in the summer). I also have a ZooMed heat pad on the underside of my tank, but I don't see a huge difference temperature wise and with the frogs being tree frogs, it's probably not necessary. I haven't heard of heat lights damaging the eyes of frogs, although I have read that some fluorescent or UVB bulbs can (it's up for debate). I do have a Repti Glo 2.0 (for plants) and 5.0 light on the tank. However, I do not use them very often.
