No special training is required. Just be sure to only fill it with disel gasoline. If not you can wreck your engine.
This depends on a number of factors. A CDL is required if the vehicle has air-brakes, I don't remember the weight limit but I believe there is one. The most important factor is if its for personal use(You don't use it for commercial use, or make money off it in any way) Then a CDL is not required.
Depending on what services as a mechanic you want to perform diesel training is not required. Today there are many SUV's that are diesel so to be competitive it is a good idea.
I would recommend the Diesel 366 piece set, which is by Craftsman, and has all the tools that are required for Diesel repair.

Only special built cars. You could run a pre-07 emissions diesel vehicle on jet fuel - if you did it to a diesel with a Diesel Particulate Filter, you'd ruin the DPF within an hour of operation. However, doing so would be illegal, as on-highway diesel engines are required by law to run #2 ULSD.
