Congratulations :-)

The easier heroics are: CoS (Culling of Stratholme), Utgarde Keep, Violet Hold (depending on which bosses you get - Xevrozz or whatever his name is, can be a pain until you get decent gear and the water boss too, until you know the strat). Also, HoL is pretty straight forward after the Ionar nerf, assuming you have a shaman in your group (for resistance on Loken and ionar).

Good luck! :-)
