Lots of work. Hopefully the tub is solid.
Everything else is easy.
Get the brakes done first. Stopping is always more important than starting.
Be sure to oil the cylinders before turning the crank by hand. If the engine is free, change the oil, clean and re-gap the points, and slop some fuel into the carb. Chances are it will start. If not, you're into a teardown.
If it starts, shut it down and do a full tune up and fluid change. Don't forget to put a new thermostat in as well.
Steering is next. Probably shot. Rebuild kits for both the box and bellcrank are available.
Fluid swap in all boxes.
Spring bushings and other suspension issues.
There are a number of upgrades for the steering and brakes that would serve you, but I would get it running and on the road first.
Don't forget, there is a CJ section that is helpful.
The guys over at earlycj5.net are the bomb as well....
