Glad you made it to a meeting, geneva. Regarding the "god" thing--one of the sayings you'll likely hear at Alanon is "take what you like and leave the rest." So if that part doesn't ring true for you, just let it slide by and focus on what does resonate.
I'm not religious either, and I was somewhat uncomfortable w/that portion of the meetings in the beginning too. Eventually I decided I was serious enough about getting help for myself that I'd take it wherever I could find it, even if the source wasn't "perfect", in my eyes. You might feel the same over time.
