You can have your lip pierced basically anywhere, top or bottom, as long as you're not going through any blood vessels. Many people pierce their lip off to either side on the bottom, on both sides of the bottom ("snake bite"), or centered on the bottom. You can also have a "Monroe" done, which is a piercing over your top lip to the left or right side (it resembles Marilyn Monroe's famous beauty mark). All body piercing should be done by a trained professional body piercer.

Don't do it yourself. Go to a person who knows how. This is not something you want to do wrong because it could ruin your lip for the rest of your life. But if you were to pierce it yourself pierce it from the outside going in.
Nope. They just pierce it. Anything they could use to numb your lip would cause it to swell up, making it hard to pierce you accurately. Besides, it doesn't hurt very much.
No you need to go to a professional piercer
Yes you can. Be sure to go to a pro and let them know before they re-pierce it. == ==
