Advance Payroll and my wife H4 visa issues

[IKureshi]

Hi Friends,
I have some question regarding my green card process and my marriage. Actually I am on H1b visa since Feb -2007. I have valid H1b approval till Feb-2013. My visa stamp was expired on Sep-2009. I did not travel to India last 4 years. I have applied my green card process on Nov-2009 in EB2 category so my priority date is Nov-2009. I got my I-140 approval last year and waiting for current date to apply I-485 now. As you know the current EB2 date for India is Jan -2009. I am planning to go India for my marriage but I am afraid as there are lots of rejection cases in H1b re-stamping. So I don’t want to take a risk for re-stamping. I have following questions to ask you regarding my marriage and green card process and I assume my green card priority date will be come in next 1 -2 months.
1 . Is it possible to go India for my marriage on Advance payroll for 2 week and come back without stamping?

2. If I go to India on Advance payroll. Is it possible for my wife to come USA on H4 Visa? And how can I add my wife name in green card process as I will be on Advance payroll.

3. Can i add my wife name in green card process before I-485 approved?

4. What is the process time for approval of Advance payroll, EAD and I-485 approval?

I really appreciate if you can give me the answer of above questions.

Thanks!
Regards,
IKureshi.
