Now that WOTLK is out and everyone has so much experience with BC, I was hoping for some advice on what I should do now that I'm 60 on bonechewer.

I've just experiencing BC for the first time (no WOTLK yet) and all 5 toons (pally, priest, 3xmages) have just dinged 60. I don't know whether I should set to work on the dungeons for gear, or forget it and focus on getting to 70 or 80. Not really doing pvp with this team. Is there any benefit to going through BC slowly and gearing up my guys? Should I straight quest to 70 or 80 and worry about gearing later? If questing is the way to go, is there any guides that I should be using? (I'm sure this has been talked about here, but I can't find it for the life of me - on multiple varied searches).

Thanks for any advice.
