Ahh the epic trip

. It's not a terribly long walk, I did it with my hunter at around your lvl (and my rogue) and I RPed the whole trip lol. People loved it as I did and said everything in character.
Go to Darnassus (the big elven city) then take the portal to the Ruth village. Take the hippogryphs then to Auberdine. From Auberdine take the boat to Menethil (or use the NPC if he's there) and then coninue out through the wetlands. This will be your main problem. If possible ask someone to walk with you or run behind a high lvl who is going there anyway. Keep beast tracking on while coming through here. One you get to Dun Morogh you're good as Ironforge is very close. Good luck!
