Hi Andy,
I was given this advice about going to my first AA meeting. It was an open meeting, which means that anyone can go, not just alcoholics, and they have a speaker rather than individual sharing - way less intimidating than a closed meeting where everyone shares.
I was told to ask for the group secretary and to introduce myself to them and to tell them that I was new and it was my first meeting. I did. The woman I talked to was very friendly - she showed me, and gave me a bunch of pamphlets, and showed me where the coffee was. No cookies, but lots of coffee. Every AA meeting has lots of coffee LOL. At the end of the meeting, she insisted on giving me a copy of the Big Book of Alcoholics Anonymous. I tried to pay for it, but she wouldn't let me. Not all groups are like that - most sell the big book at cost, which in Canada is around 10.25. It's worth picking one up, if you can afford it.
Everyone really welcomed me, and gave me lots of advice and a lot of women offerred me their phone numbers, which I thought was really weird - don't worry it's normal.
It can be kind of overwhelming at first, but you can take it at your own pace.
I'd also suggest trying at least 5 different meetings before making up your mind as to whether or not AA is right for you. Each meeting has it's own feel and flavour, based on the group membership.
Then once you find a group that you feel comfortable with, join it and make it your home group and try to get to it's meetings as regularly as possible - it kind of gives you a home base to work from.
Good luck.
