Starting a pool league with friends......?

we will have other couples join with us and rotatate between the two houses with tables, we will have a theme for each night and everyone will bring a food or drink to go along with it - so we have that all planned out. But when it comes to scoring and keeping track what should we do? It will be married couples as teams of two- so I'm thinking just playing doubles each time and just mark who wins each game and giving points for that, then extra points for 8-ball breaks and table runs, minus points for lack of theme support......then just total up all points at the end of the season and see who wins?????? Does that sound good for scoring...am I missing anything? The score sheets I looked up online look to be for single players only and are kind of confusing. We are having a trophy made also, that you will be able to add plaques to each season, for the winners to take home till next season, and possibly a "Banquet" at the end also.
