You have 2 options for the heat bulbs. You can get the 75 watt bulb and just use it, or you can get the 100 and the hydrofarm thermostat ($30) and regulate the bulb (this would be safer and keep the temperature better just make sure that the light dome you use can accept 100watt bulbs should have a ceramic socket not plastic)
There are a few threads on here about keeping humidity up in glass tanks. I will see if I can pull up a few. The basics are to cover up as much of the screen top as possible with a wet towel or aluminum foil and to most the cage.
