Changing the fuel filter I think is the biggest thing. Dirty fuel getting to the injectors not only destroys the injectors but has potential to destroy the engine.

Oil/Filter, Fuel filter, transfer case, front and rear diffs....Should be good to go after that. Maybe pick up a fuel additive if you like running them.

use only Baldwin PF7977 fuel filters. most Cummins commercial truck shops carry them.

carry one in the truck for that bad load of diesel, guaranteed you will get a load of cat piss diesel.

Change ALL fluids and start fresh. Run a bypass kit and run a good synthetic lube like Amsoil, and you will be just fine, and save loads of money.
