To be honest, I have been attending AA meetings regularly for about two weeks but do not have a sponsor nor have I been working the steps so I don't have really good advice to give... HOWEVER, I do want to commend you on all of your hard work!!!!!
It appears you are working so hard to maintain your sobriety and I sincerely commend you- it's very admirable!!
In terms of meetings... I would think even if you wont be there forever at least attending for that social support as you're doing would be really helpful...
