Better than a lot of native speakers I've met.

Modern Macs come with a disc that includes a diagnostic tool. I've seen
one or two comments about it not being reliable, but the few times I've
had cause to try it it's been successful.

There's also a 3rd-party product called TechTool Pro that doesn't 100%
overlap what the included tool does, but does provide several more
features.

it is called Apple Hardware Test, AHT for short, and is on the install
disks. On modern Macs it can be started by restarting the Mac from DVD
by pressing D instead of C.
Based on own experience it does test many things, but is helpless when
it comes to bad hardware errors like intermittent bus errors. I had a
17" MBP with this kind of error, and it still reported no trouble. The
Mac reliably currupted the disk (bus errors after all affect data
written as well ...).
Running fsck if you have problems will detect that kind of error.
(Start with cmd-S in single user mode and you will be given the
instructions for the commands needed.).

Still: AHT is very useful.

HTH

You also want memtest for Mac OS X to test RAM.

That confuses me. Partly because I thought the use of 'C' to boot
directly from CD was discouraged in favor of using the "option" boot
menu on all Macs made this century, but mostly from the implication that
the system cares about what kind of disc is in the optical drive and
won't boot a DVD if C is held down or (presumably) a CD if D is held
down.

Ah, yes. Anything intermittent can be missed by pretty much any tool if
you're having especially bad luck. In that case, finding the evidence of
a problem is a better course and AHT doesn't really do that.

It confuses me, too, but because, in my experience, Intel Macs boot from
the DVD when I press 'C' and and can go into the hardware test when I
press 'option' at startup, just as with Power Macs.

If you cannot afford it, There is a free version, called TecTool Lite.
Some features are not usable in this version but for what I see you
want to do I believe is feasable in the Lite version also.

Nope. TechTool Lite zaps PRAM and rebuilds the Classic Mac OS desktop.
It has no hardware analytical tools whatsoever.
