Renewal Form Questions

Hey guys, if you've done your renewal I could really use your help on a few of the new questions on the forms. I called USCIS but they keep telling me "We can't tell you what to put on the form." So I figured, why not ask the real experts, you guys lol.

For Form I-821D:
Question 9B, where would I find my passport number? It says "No. of Passport" next to the number that appears on every page of my passport, is that my passport number?

For Form I-765:
Question 15, it asks "Current Immigration Status (Visitor, Student, etc.)" What do I put for that? Is "NO LAWFUL STATUS" appropriate even though I am renewing?

For Form I-765WS:
I just got a part-time job a month ago so how would I calculate my annual income?
Same question for annual expenses.

General Question:
How long did it take for your renewal to be approved?
Any other new things I should know about before turning this in?

Could really use some help guys.

Replied to your PM.
