Other things to consider:
1) When playing an elimination game, it should be all hands on deck. A more aggressive pull rating for your pitchers, and everybody available to pitch in the bullpen (unless it's not a game 5/7, where you'll need to hold back a SP for the next game).
2) Cut back or (better yet) disable position player rest settings in the post season. Everybody should be available to play every inning, no matter the score. The only in-game replacements should be due to pinch-hitters, pinch-runners or defensive replacements. But nobody should be removed from the game to "give the starter a rest".
3) Adjust your base-stealing settings according to the other teams catcher.
4) Pitching tends to be a little more important in the post-season. Better pitching --> less scoring --> each run is more valuable. Put some thought into how aggressively you want to bunt.
