First, the heating pad will not necessarily be sufficient unless you are in an extremely warm room. If you are in a room that has air conditioning or slightly cooler temperatures then that will cool down the air temperature in the tank. YOu might consider getting a moderately sized bulb (blacklight would be good for all times of day). Keep the bulb on one side of the tank so that it will allow for a cooler end, for good thermoregulation.
To boost it's humidity, you can either mist the cage daily, or put the bowl directly under the bulb. Also, if you are using a screen top, try something like a hard top. Hard tops help to hold moisture, as well as heat. Screen tops are not sufficient for animals with these types of requirements, unless you have them in a special room for these animals.
good luck,
