If the Nova has been driven daily and maintained, it probably will not need anything special. Change the fluids if they are getting close to being due and make sure to check all safety related items (tires, brakes, lights wipers etc).
If the car has been sitting for a while, take tools for basic repairs, duct tape, gasket sealant, wire etc. You may also want to add a set of gauges just in case also...
The car and drivetrain combination you have is probably one of the most reliable ever built. Good luck on your trip.
