Lifting an 84 Chev 4x4

[danielw]

Hi I am currently looking at buying a 1984 chev. 305 engine. Its got 4x4 with front warn locking hubs and the body and engine are in mint condition. anyways my questions is what would I all need to do a proper lift thats 6" or bigger. I'm talking a suspension lift. These are some questions I need answers or help with:
-Do I need a body lift as well to go with it?
-how do i legthen the steering column
-do i need longer drive shafts
- longer brake lines?
- how much back spacing
-what tires sizes would look best or should i be looking for
-rim size. whats easy or most common and low cost
-along with the four add a leafs for the suspension lift do I need any other suspension additives, say new shocks or what (I always see a shcok attached to the axle or something to help steering, steering stablizer maybe?)
-anything need to be done to the axles?

sorry my stupidity or lack of knowledge but i'n new at this adn don't have very much experince or money for that matter. by the way i've got a small budget so try to keep part ideas on the less expensive side.

thanks, dan
