Welcome GreginND. I am in New York State near the Canadian border near Lake Champlain. We are zone 4 here so it should be similar to you there. It is a lot to go through, but if you follow my thread here http://www.winemakingtalk.com/forum/f25/champlain-valley-my-vineyard-19820/
I document my vineyard from beginning to now having a commercial license for about 2 years.
Begin with your USDA hardiness zone rating. There is a new improved tool for determining it. Just google USDA Hardiness Zone and go to the USDA site for it and check for the interactive tool.
My boys just withdrew their offer on a 27 acre farm about 25 miles away from me after deciding they want to help me more first to learn more about the whole process before striking out on their own.
Good luck, you have a lot of work ahead of you!
