With the "point size" corresponding to the em. In a 10pt font, one em
equals 10 points. The actual height of most letters will be smaller.

I knew that. ;-)

In other words, given a 10pt font, there is no way to determine how tall
or wide any of the letters are. (E.g., they could be 10pt, 1pt,
1000pt...) This is very helpful. :-/

Still doesn't help me figure out how wide the letters of Courier 10pt
are. (Being a monospace font, all the letters should be the same width...)
As I say, it appears to be exactly 6pt. But I have no idea why...

The size of a font refers to its height, not its width.
(And the "height" is that between two baselines in the font. The font
graphics themselves can go over those lines.)

I had a vague recollection this might be the case.

That at least makes some kind of sense...

And there is 72 points to the inch.

Depending on who you ask. ;-)
(PostScript assigns 72 points to the inch, TeX assigns 72.72, and
apparently other systems assign yet other values.)
Fortunately, in this instance I'm only interested in PS.

True ask me, I worked in printing just after hot metal went out of
fashion. LOL

Ok: how many points in an inch?

I did a simple test: I used Open Office writer. Selected Courier New and
type as many spaces as I could fit on a line. There were 66, the ruler
showed that that was in approximately 16.8 cm. So we have
66/(16.8/2.54) characters per inch. Or about 9.9786.
Great. Minor detail, the font size is 12.
