B2 visa extension questions. Please help

I submitted I-539 online last night for my parents. I have some questions:

1. what supporting documents I need to send to them?
2. Do I have to send the oringinal I-94? is a photocopy good enough?
3. Can my parents go back to China before their oringinal I-94 expire? (if the process of the extension taking too long, I may have them return to China before get the USCIS decision)

Thanks a lot!
