The upright uppercase Greek should only be taken from lbme
if you do not have the Lucida Bright Expert set.  Otherwise
it should come from lbmr for that very reason.  Then you get the
bold from the corresponding lbmd. (There are other reasons
not to use the upright Greek from LBME, including the fact that
their hinting in LBME is slightly compromised by being in the company
of all those huge delimiters).

Right.

Wow!  Script is not Calligraphic!  (An amusing feature of CTAN
is that under /fonts/calligra it has a Script face).  Does anyone
ever use lowercase Script (or even lower case Calligraphic)?

In the TeX world e are used to (i) misusing Calligraphic where 
Script should be used and (ii) confusing Script and Calligraphic 
because CM has no Script face..
