I just did mine last weekend. It was actually quite easy with the help of a friend. Did all four shocks in less than an hour. The toughest part was unscrewing the two nuts that lock together on top of the shock. It was useful to have a thin 17mm stubby open end wrench to hold the bottom nut. It was just an awkward position to be in holding the wrenches. My buddy helped by holding the screwdriver on top so the shock shaft would not turn. No advice on rotors...haven't done those yet.

'99 S420 - Rear rotor removal
I agree, "2 pound short handled sledge hammer. Hit it hard!" This is just what I had to do after using three different types of penetrating oil. Job is all done, overdue by three weeks.
Thanks guys.

yeah, i finished it awhile ago so to leave so abruptly, i used a hammer and some PB blaster got them off, eventually i had to take a grinder to it and remove the rust where the rotor meets the hub as it was causing my rotor to be offset, i had to reset the parking brake and after that it was done. i didnt end up doing the replacement on the shocks seeing as how they really weren't leaking..
