2nd FP questions for all friends on line

I got the notice for the 2nd FP. However, I have several questions for you all, please help me.
1. My passport is in the process of renewal (It will need about 1 month to get it). So must we bring passport for the FP or can I use other ID? I have whole passport copy though.
2. Can I do the 2nd FP about 1 week ahead?
3. I know this question is silly, but if you know it, please give a hint. Usually how long it will take to have USCIS final decision after 2nd FP. I was informed that my NC was cleared.

Thank you very much and have good pig year!
