So im a lvl  druid and need to get from the barrens to the silverpine forest for a quest.  How do I get all the way over and up there, the easy way

Well you need to go to Durotar and take the Airship outside of Orgrimmar to Undercity. Then follow the road south and it will take you directly to Silverpine Forest.

When you leave Orgrimmar go east and you will come to a Zeppelin tower. Take the one to Tristfal Glades (might also say that it takes you to Undercity). To make sure you're taking the right one, ask one of the goblins there and he (the one that goes to Undercity has a male goblin next to it) will tell you this is where you need to be to catch it. When you land, follow the road southwest and it will take you to Silverpine Forrest.
