I'd recommend someone just starting heroics to prioritize VH, Pinnacle, and Old Strat for the great epics you can get, as well as UK and Nexus for badges - and the Nexus has a good helm, too.
I hit 80 and that day was tanking Heroic Oculus. At 514 defense, and well lets not talk about how "much" health I had. Only died once the first trash area (someone pulled the next group during the fight) and once on the ring boss - the rest were on the drakes on the final boss.
That said .... I'd prioritize mostly the same way:
Nexus, VH, Utgarde, and CoS. If you've got a few hours at a time, in that order. Hit Nexus, hearth, hit VH. Fly to Utgarde and do Keep and Pinnacle. hearth, Culling of Stratholme. If your hearth isn't up, and someone has the key, go do Onyxia, then hearth back to Dalran.
A few runs through that sequence and you'll have the badges for some nice upgrades such as the Libram of Obstruction (15, so first cycle) and the badge neckpiece (40, so maybe the third run). If you are lucky you could also have the Helm, Shield, Sword, Legplates, a proto-drake, and Lavanthor's item. No, that didn't happen for me.

I'l still waiting for every damned one of those. Well, maybe not the shield, I made the TSW. Curiously, it still has not dropped.
Oh, and you'll earn something like 8000 rep per cycle. I'd say Argent Crusade and/or Wyrmwrest would be good first choices.
