Employment Based Greencard

Hi,

My PD is Nov 2017 and i am in EB1C India category. Besed on Aug bulletin, my date is current and I am suddenly starting to gather required docs and fill all the necessary forms. Can you please help me in listing these down?

Forms:
I-485 (of course)
I-765
I-131
I-944 (I saw this new form while going thru 485 instructions; but is it necessary for my category?)
I-864 (I saw this new form while going thru 485 instructions; but is it necessary for my category?)
I-485 Supp J (I am confused with instructions for this one; earlier this was for candidates switching employers. I am continuing with same employer who filed my 140. Do I need this one?)
I-693

Supporting docs:
Passport copies
Visa
I-94 (is latest I94 enough or whole history ?)
I140 approval
Visa Approval notices
Birth and marriage certificates
W2 (how long back ?)
Tax return (how long back?)
Payslips (how long back?)
Bank statements ?
Credit reports ?
Employment Verification letter

Anything else ? Any help is greatly appreciated.

I am in Chicago area; if you know any good attorney, please let me know. I feel like I am going to need one.

Thanks!
