My settings:
As an explanation, I play a light managerial style, only interrupting the AI manager when I need to hook a pitcher or steal a base I think the runner can make, or make a sub they're not doing that I think they should, so there are lots of pauses to enable me to step in. I also like a cinematic view of the game, so the camera angles are either close or wide and the action camera is active.
I play with very small teams in very small markets, so I've increased player size to 120% to give the game that up close in the good bleachers on a slightly-too-hot summer day vibe. (until it gets fixed, there's a small bug where the ball doesn't change height to match the pitcher's, setting players back to 100% size will eliminate it, but give you a more MLB-style view of the game)
I use Silvam14's historical parks, so if you're using the default parks, you won't have some of the camera angles available that I use. (Set Pitch cam to CF Close if you don't have an option for the angle I use)
For sound, I use kcstenglesr's small field sound set, available here:
