Here is a thread with some information on front end bushings
W124 Front Control Arm Bushings
I've heard some people say that you should have an allignment whenever you mess with front end pieces (R&R). I would tend to agree, going through tires can get expensive.
Not sure about your car, but getting the control arms off and on can be a dangerous task if you need to remove the springs (use correct spring compressor). Sway bar bushings should straight forward and fairly easy.
Not sure if you need a press to get your control arm bushings in??
I would do a search on the subject, this has been written about many times.
