Family Visit Visa/Residence Permit after marriage.

I am an American. I am over 60. I am currently in China on a one year multiple entry tourist (L) visa.
I am planning on getting married end of November or early December in China to a Chinese citizen.
Once we are married I want to apply for Family Visit Visa/Resident Permit.

Do I go to the Public Security Bureau where my certificate of temporary residence was issued and apply there? Or do I go to Immigration?
What documents will I need?
What documents will she need?
How long will it take to recieve the Family Visit Visa/Resident Permit?
Is it listed in as a seperate Visa or part of the Tourist Visa?

Thank you for your response. B.G.
