And in case it's not immediately obvious in game (this is all new to me) how the hell do I add an all star game?
Import any time during the preseason before the first game of the season is played. I generally do it at that point like you said after doing everything else in the preseason. There may be some "except"s or "but"s if the starting date as noted on the schedule screen is something back much into March or if your season should begin in March, however I'm figuring that is not an issue for you.
For the All Star Game, on the edit schedule screen there is a button "Allstar Date" that you press and can then set the date for that game.
