You'd go broke trying to apply preventative maintenance to all the parts that could go bad...on any engine.

The best list I know of might be to look at Jake's cpo program as he does a few things in a preventative way to try and make sure that his IMSR doesn't get blamed for a failure when it really was another old part that failed. His cpo program is:
-Update the IMS bearing with the LN/ FSI unit
-Replace the water pump
-Replace lifters with FSI updated units
-Replace chain guides and vario-cam wear pads
-Replace clutch assembly
-Replace AOS
-Replace RMS with 997 unit
-4th and 5th timing chains replaced
-Install new LN Engineering lo temp thermostat
-Install LN Engineering Spin On Oil Filter Adaptor (SPOFA)

The things that jump out from that list are the IMS, RMS, water pump and AOS. What mileage to do them though...no clue. My swag 60-75k or when you do a clutch job.

And do the oil change at least 3 times as often as the maintenance plan says.
