Unless you're going in with a really fantastic group, you will get smashed in Heroic anything, right now. You have the right idea, regarding getting the rep, with Wyrmrest (back, boots, and enchant)--also go for Sons of Hodir rep.
Really, you should be focused on the rep, and maybe normal dungeons. You can use the normals to familiarize yourself with the fights.
You can try the Heroics, with your friends, but you won't be contributing much to the effort, at this point. In other words, they'll be carrying you...and, unless your healer friend is uber-skilled, there will be much wiping!
Others will no doubt inform you of your shortages in stats, gear, enchants, glyphs, etc. I'll just point out one...your defense...you need 535 before you should even consider going into a Heroic!
