Yes, from what I hear, /lastname works at level 20.
As for mine, I'm going to be Aarthar Pendragon (such a rip off, I know... hehe)
Edit: Also, from what I understand, you can get yourself a special title, such as "Gnoll Killer" or something of the like for each species in the game. You just need to kill enough to get the title (and enough is a crap load; like 200 / 250 +)
