if your at lvl 50 have a mage port ya to shat then ride to hellfire pen. make sure to talk to the fp ppl there along the way and you can go to the inn in honor hold to learn your final skinning. cant remember right off hand if their is a trainer in shat but i do know there is one in the inn in honor hold. gettin the fp will help ya once you get to 58+ to make your transitions in hellfire quicker.
