Love LA Atlantis, actually. I think their bless units are wonderful, they get little harpoony fishies to hold enemies in place for the nasty spells their nation gets, and they and Mictlan have a lot of options for returning to the sea so that R'lyeh doesn't maintain sole dominance. I think if you play a practice game or two before we get going, you'll find they're better than advertised. I was pleasantly surprised.
As for the questions:
1) No graphs. Having them wouldn't be much fun, would it?

Let the knowledge be shared as it's garnered in-character.
2) I can do a collect-and-distribute on e-mails if people like. Just remember that all alliance-building prior to game start HAS to be done on the public IC thread. After that, use the IC thread for public missives and private e-mail/game interface for private missives. Ideally, you'll all save your private missives and post them to the IC thread as retrospectives once the game is over.
