Im considering a start in December of 1939.
I havnt selected realism settings yet, simply because i have not run the game.
but if i go by everything i had when i last played i will have full realism except map contact updates on to make plotting attacks a bit easier.
EDIT:
Sh3 commander will select career length, upon completion of the career, a new commander will take over the boat the year the first career ends and so on and so forth until the boat is sunk or the war ends
