Caste, I think, is the trickiest thing about this idea of converting to Hinduism. One cannot choose one's caste...so how does a person born into a country that has no caste system (or no explicit caste system, anyway), get one?
Supposedly caste is not as important in India anymore, but I'm pretty sure it still has a lot to do with who people marry, what kinds of jobs they do, and what their names are.
Caste and region both play a part in how one would express Indian culture.
India is a huge place and there is great regional variation. How can I behave with an Indian culture if I don't pick one of these regions to focus on? The food, clothing, language, and dance are all different.
Imagine someone outside America who loves American culture and decides to emulate it. Would he choose mid-west? South? North-east? West? All are tremendously different. Of course, living in his own country, where his neighbors probably know as little as he does, he could blend them all however he likes.
That's mostly the direction I go so far, but I'd like to focus more.
As far as the caste goes, I do not think I can just pick one. If left to pick, wouldn't all converts pick the most revered one? Could I look at my family and where I came from to determine what caste we might be labeled as? My own immediate family are intellectuals, however their parents were more working class. In America these things change too much based on the individual.
This problem of being too spread out will really come into play when it comes to ceremonies. Weddings, baby names, things like that are affected by region and by caste.
If I can become integrated with a particular temple then I can take on the culture it comes from. That's my general plan, but I still have not been brave enough to go to the temple I found online. I was supposed to go tonight, but I already know I will not have the courage.
