Just be careful with giving the players bonuses for winning games, especially for army size and points! I was in a campaign where that was used, and it ended on campaign turn 2 due to one team having one most of the games and just had so much more points than the other team it wasn't even funny. (Part of the problem was that wiped out units counted as destroyed, and players's army size were reduced in points by the amount of the destroyed unit.)
The amount of points you have should help keep that from becoming too crazy, but just keep it in mind.
Good luck!
