Did you, or anyone else, calculate whether the wiring is suitable
for this first?

What calculation would that be ?

The rather obvious cable sizing calculations. Had the wiring caught
fire during this "process of elimination", which presumably lasted
for some time, you might have been in a difficult position.

I have 4 TFTs - no CRTs - a small laser printer and couple of
hub/routers + a max of 8 workstations.

Sounds like you need the specialist advice of an electrical
designer.

Looks like a non RCD ring + indivdual on/off for each workstation is
the way to go ?

Possibly.

The leakage current isn't affected by whether there is load or not from
the power supply. And yes it is fairly easy to get hold of 100mA RCDs.

just don't expect screwfix to stock them. However screwfix do stock
plenty of 1 module RCBOs which you could then use to protect your
socket circuits that don't feed your office.

Still worries me that the mcb was tripping.
