If you are mechanically inclined then you can work on this truck. Read the stuff nick mentioned to get you a good base to understand these trucks, they are great but they are their own breed!
As for your question about oil, I run either Motorcraft or rotella conventional diesel 15/40 and I do put in a quart of the Lucas pure synthetic every change. I'm in Texas and my requirements are going to be different than yours though. If you go with synthetic oil I wouldn't worry about additives... (Although I would continue to use additives in the fuel.)
