UV should not be needed the way i understand it. They are nocturnal, so they dont really experience it in the wild. I guess if the break is healed all he can do is suplement to try to strengthen the rest of the bones and try to prevent it from happening again. As far as feeding, we feed ours dusted crickets most the time, and keep some meal worms in a dish some times too. Try checking the care sheets here. I dont remember what they had to say about it really.
