I replaced my sway bar bushings at 75,000 miles because I was getting a "thumping" noise when hitting chuckholes. What symptoms are you having that makes you think you need to replace suspension parts?
I don't know about the 210 chassis but sway bar bushings do wear out between 75-100 k miles on the 124 chassis and are fairly straightforward to replace (at least the fronts). Unless the 210 chassis is much different than the 124, I personally would doubt you'll need to do much else, but I am not a suspension expert.
Got my bushings from Fastlane and they were MB OE, complete with the star, so use Fastlane without reservation...
