Assuming all the bushings and ball joints are toast or near toast? AND you didn't want to do the whole thing at once...........

1) Guide Rod mounts and guide rod bushings. Ball Joints. Lower control arm bushings. Idler arm bushings. Tie Rod ends. IF these are all bad, they should be replaced at one time. The guide rod mounts/bushings, tie rod ends and idler arm bushings can all be replaced without any special tools AND without compressing the spring.

2) Bilstein shocks

3) Upper control arm bushings and sway bar bushings. The upper control arm has a built in ball joint, I don't think I ever had to replace the uca in my prev 300D even w/438,000. New uca bushings were pressed in.

With the kind of mileage you are describing I doubt you need any uca work yet. More likely is tie rod ends, guide rod mounts and bushings, idler arm kit and maybe lca bushings.
