Good question! I've heard providing UVB lighting for them is good, while maybe not essential. But they will often bask under it if provided. I've got a ways to go, but will be planning to provide UVB once it comes time to design a permanent enclosure.
While they are curious, I don't get the sense that they're particularly destructive, so I'd assume inside is fine. But would be good to hear from the experts to confirm.
