Hey man -
For the tracks, I used the following sources:
OBDR - GPSXchange.com
Divide - Cannonshot's tracks from ADVrider - see his big thread.
TAT - bought and paid for from Sam who made the TAT.
They are all easily available to grab yourself. I did very little map prep other than loading those tracks onto my Montana. I spent most of my prep time on bike and gear set-up, and the gamble paid off... we got lost basically never and were off course for maybe an hour out of 30 days' worth of riding.
I haven't had time to edit the logs from my Montana. That will take quite some time, as my Montana likes to randomly insert 600 mile / 10000mph via points every so often into every single one of the tracks.
