I haven't examined others, but imagine most standard combis such as
Bosch Worcester are similar to fit. True?

Probably. You can download the service and install manuals for most
boilers from the makers web sites.

Is a condensing boiler significantly more tricky to fit? If so, how?

Not really. The only main difference are the need to provide a drain
connection for the condensate. When you drill the flue hole you need a
sight upward slope on it.

Is there additional specialist equipment that I'd need?

Over and above that required for any other boiler? Not that springs to
mind.

How big & intrusive is the plume from a condensing boiler? I've never
seen one in action.

Worst case would be about as bad as a kettle boiling.
