I would like to see Tamara develop a little more too. I thought she was just going to be a throw away character after the pilot, but she's had some really cool moments.

Agreed on Barnabas - he's a bit one-note, but then we still don't know what his motivations are. Plus I really like Marsters, I'm glad he's able to play a role that's different from Spike on Buffy & Angel.

I thought the ID of Joseph's guide was a good twist. It makes sense: Heracles is pissed at Adama, why would he pay her to help? She knows who Heracles is because she found him in the real world for Adama, and she knows he's spending way too much time in VWorld, so it does all kinda fit together.
