1. You can select all by one command:
\usefont{T1}{guopa}{u}{n}

2. You can switch just the font series (NFSS will supply alternative it it
is not available for current family):

3. Define \textub:
\newcommand*{\textub}[1]{{\fontseries{u}\selectfont #1\/}}

I do not understand what exactly you need. First you must have the .fd
file. If you wish to have your family as default, you can do it similarly
as in times.sty, e.g.:
\renewcommand{\rmdefault}{guopa}
You should also define command for switching the extra font series
similarly as above. The style as well as the .fd file must be in a
directory where LaTeX expects such files. You find the list of such
directories by
kpsewhich -show-path tex -progname latex
If the directory is preceded by !!, you must ru mktexlsr after inserting
the files.

It's pretty the same with LaTeX.
