i found it best to attend meetings where and when theres one happening.
when i first got sober, like MLDS1, i was in small town and didnt have many in that town-just 4/wk. i hit them then started venturing to neighboring towns where there were meetings.
its hard to say which meetings you should attend. i think it would be wise to pick one and go. however, if the listings you have happen to have a key for them describing what type of meeting they are(bb discussion step study, open,closed,topic...), i suggest a closed step study to start.
when there ask if they have a meeting list/book available. if not ask if they know where you could get one.
