I really would like to know exactly which bolts/nuts should be replaced and which not for the front & rear control arms. Oh, and torque specs too.

The M3 rear camber link is made of aluminum, as opposed to stamped steel on the E9x. The link's attachment point at the subframe is thicker, and the needed bolt is longer. If I had double-checked the parts diagram, I could have seen that the bolt is different on the M3. Stupid mistake on my part.
AFAIK Steve re-used all hardware when installing the front M3 tension struts and control arms.
Have you considered getting the BMW ETS [Edit: I meant TIS], in order to get torque specs? Not to mention rules of hardware re-use that come right from the source.
