The first time that King Mickey ever appeared in the entire series was, if I can remember correctly, at the very end of the first game, during a cutscene involving opening the DTD, and the King was in there. I may be mistaken, but this is what i can remember.
No. There are no codes for Kingdom Hearts 2. You are able to use Mickey however in some boss fights. If Sora is defeated, a reaction command can appear. If you execute the command, you can play as Mickey while Sora heals.
-Slight Spoiler-The Keyblade was appointed to Mickey, while he was under training with Master Yen Sid. The Keyblade doesn't only appear to those with strong hearts. The power of the Keyblade can also be appointed to those seen as fit by other Keyblade wielders.

The same time as Agrabah after Port Royal.
No. Terra is an original character from the Kingdom Hearts series, while Zack is originally a Final Fantasy VII character. They both appear in the video game; Kingdom Hearts Birth by Sleep.
