As LGray has said, I wouldn't touch the lamps until nothing else works. Its rubbish and dries everything out. Try it with just the UTH and thermostat first and see how it goes.
As for the question on what to have for a pet, Id say its totally up to you. People who aren't interested in (or even scared of) keeping snakes would NEVER understand this hobby. They ask what you can do with it. You don't display it like a fishtank or love and interact with it like cats and dogs. That's their argument anyway. I find that pretty lame. The only reason you should stop or withhold just for a while is if your bringing a snake home is going to make anyone at home never wish to set foot in the house again. Oh and please note, its not only about the snake, if anyone around has some phobia of rodents (dead or alive) as well, you really have to find a way to keep it way out of their space and lives. Just be considerate I guess.
