- The head, handset, HUD and tempstik. I'm not touching those - they can go back to APD. Whether it is worth having them serviced in the absence of problems is another question
Agreed. There is very little you can do with them.

- The loop. As far as I can see, that's a matter of general cleaning and cleaning/replacement of o-rings as necessary. I'm comfortable with that
Agreed. Common sense rules.

- The regulators (two first stages, ADV, AutoAir and BOV). I assume that, with the right tools, the service manuals from APD (and the internet for the Paragon), and an element of care and attention, I could do this. Is it worth it though? I only got my OC regs serviced every 5 years or so - do I need to get these serviced any more often?
Service the first stages if your IP drifts. I made the tools to do the servicing on the Apex 1st stages. Take your time doing the work, it's not hard, after all, dive shops manage it! O2 cleaning? Dishwasher. The ADV and AutoAir could be treated to some new O rings every now and then.

- O2 cleaning the cylinders. Is it still possible to get qualified to do this and get VIP stickers in the UK? I'm sure it used to be, but can't find any reference to anyone doing it now
As to qualified? hmmmmm. But there was someone with some stickers..... And if you fill your own and you know the history of each cylinder why bother. After all, BOC only clean every ten years. It's only the scuba "industry" that seem to do otherwise. Money perhaps? Or do they fill our tanks with dirty gas? I'll climb off my soap box now.....
But with servicing generally I tend to work on an "If it aint broke don't fix it" system
