I'd just go to Zangar and quest there. Then when you run low on quests at 63-64ish then I'd grind XP in instances through to 64.5 or so, you can get either CE or HH rep, or even Consortium if you can handle Mana Tombs. Then do Terokkar and then Nagrand quests, which will put you to close to 67 if not over. Then do Sethekk runs to 68 and then Blades Edge will pretty much ding you to 70. You'll still have SMV and Netherstorm untouched, if you do the quests there then you'll get over half your epic mount cost -- or enough money to skill up your crafting tradeskill and make yourself some epics.
