EAD / AP Renewal - FAQs

Guys,
Since it's time for EAD/AP renewal for filers from last year, I thought it will be nice to have some FAQ thread.
Just starting it like blank for now and moderators/experts can update it as needed:

1. When should I apply for EAD/AP Renewal?
2. How long does it take for EAD / AP Renewal?
3. List of documents need
4. Is Fingerprinting required for renewal of EAD/AP?
5. Will the renewal be one year or two years?
6. Can I apply for renewal of EAD while out of US?
7. Can I travel while EAD renewal is pending?
