I use the Ford Motorcraft Diesel oil. Mainly because it's specifically designed for our Powerstroke engines. It has all of the chemicals and compounds that are vital for our engine, but by all means get whatever's comfortable to you. They all work.
Water Pumps are prone to failing in our engines (the 7.3L) around 150k miles... It's recommended to get the Bosch Water Pump, for about $140, and a diesel site 203 degree thermostat, about $30.
