Look in the font file. It can be converted to human readable with
probably several things. I use fontforge.

Correct.

The PostScript Courier font is hard-wired into the printer. I have no
idea how to get at it.

Much experimentation and many trees later... ;-)

Note that the block had to accomodate not only capital letters, but also
underliners, as well as accent symbols above capital letters; so if the
capital letters are 5.5 pt in height, a block height of 10 pt appears
realistic to me.

Exactly.
There's some meta-information in font files though.

Typewriters typically used a spacing of 10 or (less commonly) 12
characters per inch, i.e. a character width of 7.2 pt (10 cpi) or 6.0 pt
(12 cpi).
With 10 pt and 12 pt being the most common nominal font sizes on
computers, it makes sense to design a pixed-pitch font to match the
common typewriter pitch of 7.2 pt (to be able to print on forms
originally designed for typewriters) at a nominal font size of 12 pt, as
this also allows to emulate the 6.0 pt pitch by simply changing the
nominal font size to 10 pt.
Hence the exact 6 pt pitch of the Courier font at a nominal font size of
10 pt.

That's actually not true - at least not in practice. Instead, word
processing software will usually adjust the line spacing to some other
font properties.

The traditional US-american printers' "pica point" was defined for one
pica (12 points) to be 0.166 inch (giving ca. 72.29 points per inch).
TeX, being quite traditionalistic regarding typesetting, probably bases
its definition on this older standard, although I'm quite puzzled why it
uses the slightly lower value of 72.27 (not 72.72). Maybe it has to do
with the evolution of the inch since the day the "pica point" was
standardized. Also, there seems to have been alternative suggestions for
the definition of the pica point back in the time when it was
standardized in 1886, one if which would have resulted in exactly 72.27
points per inch.
However, /the/ "DTP point" gives exactly 72 points per inch, and any
software using a different definition is a rare exception.

So, have you found a single guide which answers all your questions? I'm
interested in learning about it too.

Nope. In the end, I had to measure the metrics emperically. Google was
useless.
