Vehicle is 79 F100 4x4 LWB 302 engine RHD. I want to set it up to be a touring 4wd for around Australia.

Firstly shipping will be a killer, am currently looking into various USA to Aus companies, but any suggestions would be appreciated.

Okay so after what I consider decent amount of research I still have a few questions I would like answered, I will try and provide as much detail as possible. New to the 4x4 and Truck modifying game so sorry if my questions are silly.

Lift Kit: I am looking at the 4" BDS kit (6'' seems like to much work currently) as not a lot of good things to say about the Rough country set.

1. Should I use the add a leaf or replace the whole spring. I am leaning towards the replacement as the ones in mine are very average.
2. Do I need the pitman power steering arm the kit offers as I will be looking to fit power steering.
3. Bump stop extension kit needed? Buy alternate kit or simply make one myself? Don't want to spend all the money on the lift and have the springs give out prematurely.
4. Is the steering stabilizer needed if I will convert to power steering? Couldn't find much on this. Single or Dual as well if needed,
5. Anything else I need to consider when lifting? Replace all bushes etc? The brake lines will be replaced with braided ones.
6. Is the kit set up for LHD or is it a universal application?

Radiator/Fan/Alternator:
1. Want to upgrade with the dual fan setup, 4 core radiator and the 3g alternator. Question is will the alternator be enough to power a dual battery setup and a third for a winch? If not what alt should I be looking at? I don't know much about car electronics.

Wanting to also do Disc Brake conversion & Power steering as well as a ZF5 conversion, currently still researching. They will be my next mods.
