I would wait a couple of weeks maybe 4 or less just to make sure that it is some what healed.
If the pain of sleeping on it is tolerable then it should be ok to sleep on it.
2-3 months
You can tan right away, just keep tanning lotion and oil away from your new piercing.
You can sleep with your cartilage piercing out after the ear is completely healed up. It takes about two months for the ear to completely heal.
If its saltwater i dosent matter that actually cleans it.(:
I got my industrial about 1 year ago. The first 6 months trying to sleep on it were sore. Now 1 year later and yes, I can sleep on it but in the morning it is still sore.
2-3 months before the piercing can be submerged. You can go swimming now as long as the piercing doesnt get wet.
It depends on the surgery that you are getting, the hospital that you go to, and the type of piercing that you have, but normally they let you keep it in as long as the jewelry is not metal
The barbell is too long for the piercing and should have been shortened after two weeks, get a shorter barbell in the piercing and it should settle down.

I have long hair and a scaffold piercing..for the first week or so just make sure to clean it regularly. Also if you are worried about getting it tangled up, for the first week or until it is healed, wear your hair up or to the other side. Just to keep you comfortable.. and try not to lay on that side when you sleep! So yes, I would say go for it. :)
You can be any age as long as you have your parent's permission and they are present at the time that you are getting the piercing.
