I'll throw a disagreement out for that one. After getting all the winter fluids mixed in, don't start it unless you plan on driving it and warming up the whole drivetrain.
Completely filling the tank with winter diesel (which is certainly out at the northern pumps now) would be a good idea to keep tank condensation low.. You could throw some diesel conditioner in the tank as well, but I've left diesel sitting over the winter without it "going bad".
Trickle charge the batteries, or bring them into the house.
Make sure your coolant is mixed properly for sub-zero temperatures. If you have to add more coolant concentrate then you'll have to do something to get it all mixed in. Driving around for 20 minutes would do the job. At this temperature, idling will take a long time to mix it properly.
