The HD cooling fan had been  broken so I replaced it this past weekend but it doesn't seem to have helped. Too late? Permanent HD damage already done?

If this line is for real:
  194 Temperature_Celsius     0x0022   116   253   000    Old_age   Always 
  -       34

Then your drive is running hotter than boiling water and has been close to 
melting point of solder. In spite of that the error count is fine, but holding 
your hand an inch or so from the drive should tell you if this is that hot.

I start taking some action on fans and dust if a drive hits 45C, so your drive 
is either way hot (probably) or reporting false bad news. That spin up time is 
very long, even if that's 10ths of sec that's slow.

I would be sure that backup is good, and plan on replacing that drive sooner 
rather than later. Tonight would probably be good...
