OK. Getting this now I think. So 'contacts folder' really does the same
thing as 'address book' and this is only a nomenclature thing? Presumably
the contacts folder is in the PST file together with the actual emails
sent/received (I am devising a backup strategy, in passing). Also, if I opt
to place details of a sender in my contacts folder, do I then have the
option of toggling a setting to make their whole email address appear in
future?

Certainly not. In Outlook, there is no "address book". The Outlook
Address Book is simply a view of your Contacts folder that shows those
contacts that have electronic addresses. When I say
"contact", I mean an entry in your Contacts folder, which is where all
your contacts should be.

Most of my emails out are sent as replies to those emailing me.

That's your explanation, then. The sender of the original message
controls what you'll see in the From field and, hence, what you'll see in
the To field when you reply.

I'm sure their full email address must
be sent (or else how could I reply correctly); it's just that I can't
see the whole address in the header of the screen, or on the list of
messages. I'm sure there must be a simple option I should select, but
it beats me at present!

You don't control how the other people's addresses appear when they send
you messages. Those people with names appearing in the From field set the
Name field in their account settings. Those people whose addresses appear
did not.
