Sounds like you are on the right track.
For sure, I would add at least a heated pickup in the tank. The amount of additional heat really depends on where you live and what it takes to keep the fuel fluid so that you can get it to the engine. If you are following the basic rules of running when the engine is hot; you don't NEED a whole bunch of extra fuel system heat.
I would run a coolant heated pick up at the tank. Run the coolant lines and fuel lines together and (if necessary) insulate them together.
I use viton wherever possible, it cost more but ends the compatibility issues.
If you are interested in documenting your conversion for the benefit of the community, I have just put up a Wiki to collaborate on various WVO conversions
