Specific Requirements for Non Immigrant O extension and to extend a work permit

Can you help me understand what is needed to renew my Non immigrant O visa and work permit? I haven't found a site that actually has all the information or a complete forum response either. I can guess that the following are needed. Can someone direct me to a site or correct my answer/correct my question???

1. a copy of every page of the passport that is used?

2. Between 1-4  (4 x 6 cm.) photograph(s) with either white? or colored? background

3,4,5 papers showing my registered address which may involve getting a  copy of house owner's ID, signed  plus a form from Immigration signed by owner). Yes?

6. Do I need to show a form stating I have a bank account?

7. Do I need  Copy of registration certificate of the employer/foundation/organisation? any other papers?

8. Copy of the previous/current work permit pages

9. Non Immigrant O form filled out.

10. Medical certificate (blood check) form

11,12. Marriage certificate with notarized paper from US embassy)
