Coby just tries to fulfill his dream...which isn't exactly to be on par with Luffy (but to be an acknowledged, strong person - aka admiral). There are still lightyears between the two, and don't forget that Luffy is constantly improving as well.

For his training, I got the impression Garp never really "trained" them, but his subordinate with the Katana. That guy will probably fill the now open vice-admiral position and continues to educate both of the whiney brats.
