Yes you need i797C for the I130 and the I485 your spouse prouve of citizenship

.

you need your work permit and SSN and that’s sufficient. if you don’t have one, I’d bring receipt notices for i130 and i485

All I used was EAD Approval Letter and SSN

i don’t have my EAD Yet so I’ll probably try I-130 and I-485 NOA

You'll be fine with your I-797C for I-485, proof of residence like a utility bill and of course your identification. Your I-797 provides proof of your legal status
