I don't know if we need more Cylon Leaders. Maybe that's a character who's only in play in the 4 or 6 player version. <shrug> Caprica is an obvious main character choice, but how would they incorporate her? Do they really want a bunch of Cylon characters to choose from? All of the humans listed are marginal at best. I admit Zarek is in the list of marginal characters but they needed a third political leader and he's the obvious choice. Maybe we should look at it that way. One more character for each class? A group of characters which form a new class (besides Cylon leader)? Cain as a character sounds interesting but how do you work that? Pegasus wouldn't show up until part way into the game, would it?
AFAICanTell, if you choose to play with the Pegasus board then it is in the game from the beginning. Basically, you are playing a "season 2 game" that begins from the point the Pegasus arrives.
By the way, I think that passage you quoted from another website is in error. I doubt you will be able to play the Pegasus expansion as a standalone game.
