Yeah those 2 episodes were not up to breaking bad par. S3 in general isn't as mesmerizing as the first 2 seasons, but it's still great. I haven't seen the most recent episode yet but I'd say you're right about her getting more involved. I bet she starts turning into a bad ass just like Walt, lol.
This got put on hold for me when my GFs netflix disc is queer as folk and we started streaming Dexter.
