Others can likely provide better info but here are some off the cuff thoughts;
Inspect front A-Arms for cracks or signs of stress. If they are painted or coated, it may be worth stripping them to reveal the metal. Rear A-arms are known to fail as well.
Make use of the grease fittings to lube up the joints.
Replace shock and spring which can be sourced from PI motorsports. For mine there was some light machining work needed to attach them properly, but nothing major.
Find an alignment shop who is familiar with old Italian cars. Bump steer.
Bushings may be in poor condition. Consider cutting new from Delrin. Actually not certain if Delrin is best for this application but I have found success with it as a bushing material on other cars.
Since it's all apart, you might as well address the rear transmission support. There's a great amount of detail related to that topic on these forums. I won't try to re-hash it here except to say it's important if you'd like the car to handle reasonably.
I know little to nothing about the steering. It sure would be nice if there were a rack with a faster ratio which could be swapped for the slooowww factory rack. One day when the car is more sorted out I'd like to attempt adding an electric power steering 'helper'. They are popular in the offroad world.
