Heather, Wonka has given you excellent advice. You will also need to check on housing because it may be quite expensive there.
I think I would ask the gentleman for more information before making the trip. He didn't mention salary when you spoke to him? You will need to ask him if the company will pay relocation expenses. Some places do and others don't...so ask...don't assume anything.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
