Basically yes.  Please ignore the \lccode \uccode values and use
lowercase/uppercase for `.hcode' instead -- an important point I've
forgotten to mention is that the encoding used in TeX pattern files is
the intended font encoding (e.g. T1).  In some cases, this is *not* a
groff output encoding like latin-1!

This is a (bad) feature of TeX.

Yes.

Only for ASCII.

Yes.

I think that virtually all hyphenation pattern files for TeX use
lowercase only, but it is not necessary since TeX makes an internal
\lowercase (using \lccode values).
