Got an error message (in red, no less!) that the hard drive couldn't be repaired and needed to be erased, etc.
Ah, yes, that explains it (I should have asked that first). The HD's directory was hopelessly corrupted.
AND SO: I restored the computer using the 12/11 backup that was listed (in fact, the only one that was/is listed).
THE THING IS, THOUGH: I got the computer to boot up ok, but am missing my personal data, settings, iTunes librtary, etc.
Ah, ok, so your hardware is ok, and you seem to have a good version of OSX (it may not be up to date, though -- if it's from Novermber 2011, it will be Lion, not Mountain Lion).
All, I suspect, are safe and sound in the 1/13 backup that I can only see when Option>Browse Other Backup Disks.
Sounds like something happened between December of 2011 and now. There are several possibilites, but it probably doesn't much matter.
THUS: I guess I am left wondering that if I do a complete erase of the hard drive, per your 10:06 post above, willI then be able to (a) access, and (b) load what I need to from the 1/13 backup?
No, I'd not recommend that now.
Since you do have an apparently-good Jan 13 backup, your best bet may be to use Migration Assistant to transfer your 3rd-party apps, user account(s), and data.
You may not want to do that with the user account you're now using, however, as that may further complicate things -- you'll end up with one or more extra accounts and/or possible permissions problems with files on other drives.
And if you're now running Lion, it won't let you transfer "backwards" from Mountain Lion, so you'd need to upgrade to Mountain Lion first.
So, let's be sure we know where we are:
• Confirm what version of OSX you're now on.
• How many user accounts do you now have (and how many were on the backups)?
• Are you reasonably certain (by spot-checking) that the 1/13 backup has all your apps, user accounts, and data?
Then we can figure out what you need to do.
P.S. AHT doesn't start when I press/hold 'D' upon restarting.
I'm not sure when Apple started putting them on the HD -- it may have been after your 2008 Mac was shipped.
If you can't find it, don't worry about it now. And AppleCare can send replacements for a nominal fee (they'll need your serial number).
