To your first assumption, yep. The HD BBC channels do not currently carry the regional news 
programs, for example. Everything national oriented is (allegedly) exactly the same. Some programs 
are also moved around a bit on BBC Scotland - this may also be true for Wales and NI.

I already have an HD tuner and my policy is to give it a lower priority than the SD tuners. That way 
they will be chosen last and only used (i) whenever I specifically choose an HD broadcast or (ii) 
when I run out of SD tuners.

The Yanks call the channel name field the "Callsign", but of course that would get you blank looks 
over here. The terminology used either side of the Pond causes some head-scratching from time to time.
