Tragus piercing I need answers!?

Okay, so I really want a tragus piercing. I think they are really cute. This will be my first ear piercing (besides my earlobes). I just need to know how bad it hurts? What is the pain compared to? Should I get both done on the same day? Or get one done one day then go back a few months later? How long do I have to wait before I can change the barbell?
