Andy, can you elaborate on the air filter service. It seems excessive. Doesn't the "book" say something like "Inspect every 20 k, wash every 40 k"? You do have the washable cyclone filter with a dust trap?
For the grease points, it is better with frequent service, particularly in wet or dusty conditions. I believe it is more important to grease every 5k than to change oil every 5k.

I work on the following service intervals.
Change the oil, oil filter and air filter every 5000 miles.
Grease the grease points every year.
Check the brakes when I change the oil and change the pads when they are down to a quarter
Lube the door locks before winter sets in.
Get the injectors refurbed if the engine runs rough or after 150K miles.
Put 1 bottle of redex diesel in the fuel every 10th fill.
re-grease the wheel bearings every 20k miles.
Everything else gets done when it needs it.
You will find that most garages do a Mini service when they say they are doing a full one. Oil and oil filter are most important (as well as making sure that you have brakes), everything else tends to be nice to haves and is not likely to kill you or ruin the car. Remember the engine is the most expensive part so make sure that has nice clean oil and it will look after your wallet.
