If you are ready to go to Outland, I suggest you go to the scryer platform hall in Shatas City to learn various professional skills (you can learn various skills up to 375). If you are a newly connected trumpet, jewelry is a new professional skill in TBC version, and tribal players can also learn it when they go to Silver Moon City (novice village of blood elves). If they are of other races, they can be sent from undercity to study in Silvermoon City. You can ask the guard for the specific location. League players go to Esoda (it doesn't take too long for non-Delaney people to go to the dock by boat)
