When you're using these ELM327 devices, do you need to have your
engine turned on or should they still work with it off?

The ignition always has to be on, but the engine can either be running
or not.

Either, depending upon what you are trying to do.You can download and
clear codes with just the ignition on, or see the live data with the
engine running.

As a 'computer person' I've always been intrigued re reading what cars
have to say but not known anyone with any of this sort of kit to know
what's good or not.

I guess the computer based versions are cheaper as you don't need the
display bit but what constitutes a good one please?

In any case, what are the chances of getting anything out of a 92
Astra, a 93 218SD or a 2001 Corsa?

Cheers, T i m
