sagoldma,
I'm from St. James, which is 10 minutes from Stony Brook. The areas surrounding Stony Brook are St. James, Nesconset, and Port Jeff, all of which are nice places to live and at most like 15-20 minutes from the school, depending on traffic in the morning. There might be other towns surrounding Stony Brook that I'm forgetting, though. I believe there are houses literally surrounding the campus that you might be able to get, so you might also want to look into that. Unfortunately, the cost of living on the Island is very expensive, and you're looking at spending $10,000-$15,000, though. Good luck.
