I'm not Indian but my favorite Indian restaurant is at Bell and 31st Avenue. I frequently see large groups of Indian people there. You could probably go anytime for lunch or dinner and ask the owners of the restaurant or the people eating there. It's called India Palace and their number is ###-###-####.
Also, there's a website for the Arizona Indian community:

They have lots of events on their calendar where you could probably meet other Indian people.
Because there are so many religions in India, it's probably inappropriate to assume you're Hindu, but in case you are, here's a link to the Hindu temple:

I know it's comforting to have friends from home, but I would also go out and do things you're interested in and you will probably meet some friendly Phoenicians.
As far as figuring out how the people are in a certain neighborhood, you can at least find out if there are sex offenders close by:
