Some of this is from Ed Mayo, PCA Tech Answer Person, some is from various posts here and on Rennlist or Early 911 List, some is probably from my own head.
CV-joint repack --- Every 20,000 miles or every Two Years
Brake Fluid total replacement --- Every Two Years to yearly
Brake system seals disassembly & check -- Every Two Years
Brake system rubber hoses --- Replace every 10 years, or every 100,000
miles
Clutch cable replacement --- Replace every 10 years, or every 50,000
miles
Distributor removal, clean & oil felt under rotor --- every sparkplug
change
Distributor disassembly, inspect for wear --- Annually
Fan belt --- Inspect every oil change, Replace every Two Years
Distributor Detail Compilation:
Remove the felt center, and put drops of engine oil down the shaft
until it won't take any more (i.e. ountil the oil forms a column of
oil all the way up the hollow interior of the dist. shaft), then put
the plug back and put a few more drops of oil on it, until it is
saturated. This 'oiling' needs to be done at least yearly.
The felt has to be taken out to assure an adequate supply of oil gets
all the way down the shaft to the pivot plate.
And, yes, the 964 distributor has the same centrifugal
'synchronization' mechanism as the 3.2 distributors! Likewise,
maintenance of those moving parts, including cleaning and lubing .must
be done.

Warren -- do you think post '84 dist.s need to be completely
disassembled, cleaned and greased every 3-5 years? Your posts refere
to pre-84 cars. If not, then what should be done with the later ones
(other than the oiling).
Also, what grease -- the sticky Bosch high-temp. grease?
Repack the front wheel bearings every couple years (20,000 miles or
so), repacking the CV joints, maybe every 20 to 30,000 miles. The rear
wheel bearings are not serviced, they’re good until they’re bad.
Shift assembly and throttle rod bushings in the tunnel should be checked every few years and while you’re at it, check for full throttle operation and proper adjustment of the throttle stop under the pedal.
Lubricate the door hinge pins and door stop yearly.
Oil windshiel dwiper motor bearings - every year - remove wipers and turn on then drip oil into shaft area. Probably the rubber gaskets for the wiper shafts could be replaced every few years.
Grease manfs. say that grease ahs a shelf life of 5 years -- this may imply that all bearings, CVs, etc. should be replaced or repacked that often....
-------------------
Feel free to say what type of grease, or whatever will be best for a given task (but lets not turn this particular thread into a best oil or best grease thread).
Note that we need to distinguish mileage related items from age related items.... e.g. rubber susp. bushings will go bad, as will tires, even if they have no mileage on them.
