eek this one will be very difficult to answer. Prob a few of us have done this mission (i have not) but since were all quite new to the game too it will be dificult to find someone who can remember.
My best advice is to press L to open the quest log, check in the discription of th equest if the point you out to a area (ex: like nw from the quest giver [once again this was a example]or tell you to go south from a city or a camp)
Of what i had experienced with WOW's quest system is that they are very detailed oh where to go if you read the log. the few quests that did not mention a direction to go asked for items from mobs that i have killed before and know where to find them.
