Fuel filter, Oil and filter should be first, followed by coolant that is only good for 100k max. Brake fluid check belt. glow plugs and seals not as bad unless something is wrong. Change trans fluid and filter then front and rear diff.
That would be a good start, I bet someone will jump in help out a little more. Hope you enjoy you new toy.
just like he said, if its a liqiud, belt, hose, or filter, i would change it.

and pull the brakes and check them too, especially the inside pad, not just the outside.
