F-1 visa holder apply for GC through marriage

[christy503]

I'm a F-1 visa holder and in my first year of a 5-year PhD program. I married a US citizen last Dec. and want to apply for GC now.

Should I submit all the forms (I-130, G-325A or G-325?, I-864, I-485, I-765, I-131, I-693) to Chicago mailbox together? (I'm in AZ)

If I can pay the fees with one check, what's the total?

I'm a student, do I need to submit I-765 for employment? (I'm a fellowship student)

If I'll not travel outside US during the period waiting for GC, do I need to submit I-131?

Should I get any visa number or file number (in G-325A) before I submit the files?

Thanks
