In addition to what you've listed above, you need:
Form G-1145 (E-Notification)
Copy of Marriage Certificate
Copy of Employment Letter (if applicable)
Copy(ies) of W2s
You do not need a Police Clearance Certificate.
The more the documents you send in with your I-485 package, the less the scrutiny you get to face with the IO at the time of your interview, in my opinion.
very true sm1smom, I sent everything I had with the application, which made the interview super quick.
