My suggestion would probably be to start a DK, go tank spec, and level him through instances. By the time your 75 or so you will be exalted with all cities.

As Quests don't provide spill-over Rep post Revered or thereabouts anymore, you might consider doing Quests first till Revered and then do Instances for the rest. AV (eg turn-ins) provides Rep as well if I remember correctly, albeit slowly, but of course also provides you with Honor for the PvP ones if you are so inclined.
