When you start do the new player tutorial and quests. They will teach you how to play the game. Don't worry about what the best or most uber template is, just play one that you like and have fun with.
Also remember if you don't like the character you first make then before you get to far, delete and start again. Or just create another toon on a different server. Only don't expect to use the same name cause even if you delete the name is still in the database as used.
