the drexler clutches need no special break-in procedure. driving a twisted road with moderate speed for a few miles will be enough.

yes, absolutely. after 500-1.500km you should change the oil!

depends on usage. after 5-10 trackdays or after 2-3 years of street driving you should replace it.

the lsd is able to handle very high torque values. gearset and bearings will fail earlier... as well as halfshafts and so on.
