Smooth, I'm in your same boat! My 2nd team hit 80 last week. This week I mixed my two teams and did some heroics and some ToC. It was very hard with my 2nd team in ToC I didn't have the guts to try Naxx yet, but I will this week. I need to farm some cash for repairs. I am down to about 400g on all 10 toons, lol. Wiping in ToC is expensive.

My setup has a 2nd pally tank (dual specc'ed holy) instead of druid (though I am going to level my DK to 80 to alternate tanking duty with) and a hunter instead of 3x elemental shaman (I have 2).
