You can name them like you would any other mob, and that name will determine what player they look like.
You can befriend them by throwing a diamond at them. This also gives you the “Diamonds to you!” achievement, if you are at the appropriate progress level.
They will attack hostile mobs if holding a sword, and shoot them if they have a bow. They also attack if you haven’t befriended them yet, regardless of the weapon. (You can’t see it, but Notch is holding a diamond sword.)
I had to. You know I had to.
