I wanna think that he developed them on his way. Like he already had the main protagonists in mind and their powers, but he had to connect them in someway. He can't store that much in his brain (even Oda can't :P), it's too much.

Like the Admirals and the Shichibukai I think he already have them in mind, not exactly the characters but the positions. The World Government, the better power: the World Nobles. Don't think he had their face in his mind, but he just knew what the powers in One Piece would be. I like to think that's how it is, but of course im wrong.... That's why I love One Piece that much. It is huge.

I really like the Dragon incident, who appeared in Loguetown. And he turned out to be Luffy's father, it was like 7 years after, I think, since we learned that he is in fact his own father.

And for the trivia I'll go with MDM, our blogwhore :D. I'm somewhere around 23 myself, I think, I dunno. I remember when I found out about blogs, I created more than 15 in one month haha.
