I-130 Approved in F-3, what next when PD is available?

[NdTech]

I am Canadian Citizen, born in India. My Father, USA Citizen filed I-130 for married son during FEB-2003 and approved. I am here in USA since 2006 working on TN, current status will expire in JAN-2013. Waiting for PD to current for my F-3 (Family), this month PD is 01JAN01.

Questions,

1. I can see now PD is moving fast, any idea, how long it will continue this trend? Since all know huge backlog making impossible to assess anything.
2. What next? filing I-485? and I-846 support letter? anything else?
3. How long this procedure will take in typical case?
4. While applying for Citizenship, did my legal authorized stay in USA count? or zero counter begins?
5. How do I get work authorization for my son in University? or for my wife, now stay home? Available any alternates?

Thanks for reply.

A1: No one can speculate that. PDs may also retreat, so keep that in mind.
A2: Once your PD is current, you will file I-485 (along with other forms, I-131 and I-765 for example).
A3: Under 12 months I would guess.
A4: No. Physical presence for citizenship will begin the day your GC is approved.
A5: Once they file for I-485s along with you, they can file for EADs too.
