Ok thanks. I think maybe I associated them because both bike peeps who fit me when I was looking for bikes commented how difficult it was to get the right position for my seat and a proper reach (short legs and short arms, I guess).

That makes sense... They are related actually. If you need lots of setback that will have an effect on your reach (probably requiring you to look for a bike with a somewhat shorter reach than you otherwise would), but setback should affect reach rather than the other way around ('cause you can mess up your knees if you let your reach dictate your setback).
