Once we get the GC:
1. What is the maximum time we can stay outside of USA?
2. What permissions we have to take before we go outside?
3. Any FAQ links for these rules on the net?

Once we get the GC:
What is the maximum time we can stay outside of USA?

"A Permanent Resident of the United States can travel freely outside of the US. A passport from the country of citizenship is normally all that is needed. To reenter the US a Permanent Resident normally needs to present the green card (Permanent Resident Card, Form I-551) for readmission. A reentry permit is needed for reentry for trips greater than one year but less than two years in duration.

For US citizen, What is the maximum time we can stay outside of USA?
You can stay as long as you want provided that country allows you. You don't need any permission from US government.
