OK, I'll kick it off myself:
my preparation usually looks something like this:
I scrounge the net or pester fellow Chevy drivers for a setup, load it and do a few turns at "time attack" until i feel i know the track / car combo (8-15 laps),
i check tire temps and my driving impressions to change one or two little items in setup, though my knowledge here is very limited, that's about the point i get tired of seeing only one car on track,
another night i try to join an online race with the right combo to get a feel for the setup on a longer turn (8 laps or more if poss.),
I do not count these as a real preparation, though, because the focus is on racing, not on setup or line details,
that's about it.
yeez, by the time i had finished this text, neo and stiggy had already answered, guys you're supposed to be faster on track, not on forum! [-X
