Well, for me, it's all important, and relevant. The beginning and speaker portions yes, are redundant, and themes repeat themselves. But these themes are usually ones that people deal with on a daily basis.
The part where you break into smaller groups is good as well. Hearing everyone's perspective on a topic or reading is very good.
But, more importantly, I would get a sponsor and start working the steps out of the big book. THAT's where the recovery happens.
