The general rule of thumb is to have a UVB light for all reptiles and amphibians, but a lot of people say they don't need one for the bearded pygmy. I have a dual light bulb canopy, but I only put in one bulb to set a dark-light side. You definitely don't need a night light because they go to sleep at night and you won't see them moving. Mine goes back to the same spot everytime to let me know to turn off the light. For the temperature, you can drop it to around a nice 68-72. Just something that's cooler than what you have during the day.
