z visa and residence permit for my husband

I 'm from Lebanon an English teacher in China since 3 years and a half. I got my Z in Hong Kong. I ve just got married in Hong Kong and got the marriage certificate. My husband is from Nigeria. He has the X and is a student in China. He is going to end his studies in 2 months and his X will expire too. As now we are married, he can get the z and residence permit as an accompanying family member. My residence will expire in April 2013 and i will renew it. Please what are the requiered documents my husband needs to submit to get the Z and residence permit? Does he need to go to Hong Kong to get it? Thanks.
