Man 82K? Nice score. I would do the gears and lockers first you can all ready fit the tires you want to run. Every thing else will evolve in time.
X2, depending on wheel width and backspacing, you can usually squeeze 33's on a 1st gen.
When
1982 w/ 82,000 miles now the change begins. my Buget is really small May $3500ish
My wish list:
3.5 to 4" lift
32 BFG's & wheels
side Armour
Replace chrome rear bumper?
Gear change/lockers
shocks
change out the warn 6000 for a 8000
Line-X
With a budget of $3500, if you spend wisely, you should be able to do all of your plans, and likely have extra money as well. With the tire size you are considering, I would try and find used Toyota 4.88 e-locker equipped diffs, you can usually find them for about $600/diff, or look for a set of regeared diffs w/lockers or complete axles from a rig being parted out.
If your winch is working fine, you don't need to replace it, for the cost of a pulley and doubling back to your truck, you can double its workload rating to a 12k winch, 18k if you use 2 pulleys.
The use of a pulley/pulleys are also useful/needed when you can't make a straight line pull, when no direct anchor point is available, or when reverse winching
