Another thing I like to do when I am putting this much effort into a league is get all the stadiums right. By right, I mean replace with stadiums I prefer.
Silvam14 has a great thread where I get most from.

This will eat up a good chunk of time as I'll be doing the same for the Minor League Teams as well. If you are not concerned about neutral park factors these will make you happy as they have some pretty decent factors you can just run with. At the end of the day when I am watching a game play out... Fenway Stadium on the left just looks a lot better than Fenway stadium on the right
