Hello DZJ 
I just saw your message on travel forum. I will try to give you a detailed answer tomorrow, as it is already 12:30 midnight here and I have to get up early in the morning.
Meanwhile, you can go through this very helpful forum:

Go through the sticky topics of various subforums, you will find pretty much all the do's and dont's while living/traveling in India. Still, I will try to answer your queries when I logon tomorrow.
