Welcome! The best way I've found to heat a glass aquarium is with a ceramic heat emitter. I use them with a dome light fixture with a built in dimmer switch so I can dial in the temp. As far as lighting goes I only use compact fluorescent bulbs because they don't emit heat, don't kill your humidity, last longer and are cheaper to run. I don't use any night lamps. They really aren't necessary if you're using the ceramic heat. I definitely recommend getting rid of the analog thermometer and hygrometer and get an Accurite digital thermometer/hygrometer. They're like 8 bucks at Walmart and are FAR more accurate.
It'll take you a little experimentation and trial and error to get everything dialed in. You've definitely come to the right place for all of your questions and concerns!
