Going to India after 9 years: Green Card question

[JJ910]

I am going to Bombay for a short trip on this comign Monday. I have an Indian Passport and a Green Card. Couple of questions:

1. Do I need any stamp on my passport (like an ENCR stamp) before leaving India to come back to the US?
2. Do I need to do anything while travelling to India?

If anyone can tell me any misc. insiders about the International Airport, that would be fantastic.

Thank you.

No & no
