First no E36 has ever had aluminum control arms just the E30 M3. Second the Al control arms are about twice as much as the steel ones so unless you track your car I wouldn't say they're worth it (the Al ones are about 7 lbs lighter). 3rd, the common failure in E30s is the ball joints failing not the bushing, so therefore the recommendation to replace them every two years if you track the car heavily. The bushing does wear out though and should be replaced every time the arms are replaced.

So my recommendation, buy the steel control arms, buy the solid offset bushing of the later cars (this will give you a little more caster). More caster is good for a little more straight line stability since you drive on the highway (I'm assuming), get an alignment after the new parts are in, you might want to replace the tie rod ends while you're at it. Have the front toe set to about 1/16th of an inch total toe in (also good for straight line stability). Hope that helps.
