ext3 is really just ext2 with a not so good journal tacked on. As
such it doesn't recover very much better than ext2 does. Better to
use ReiserFS or XFS true journaling FS's. I'd suggest ReiserFS.
Doesn't help much with your problems now, but next time you
install, I'd advise you to avoid ext3. As to lost or corrupted
files, unless you have backups for 'em, I'm afraid you're SOL. You
might try lookin in the various 'lost&found' directories ext3
spread all over your system when it tried to recover.
OTOH, your corruption shouldn't have happened other than due to a
hard shutdown. If that was due to power failure, you need to invest
in an UPS. If you didn't have a hard re-set, your hard drive(s),
might be goin bad. The drive(s) probly came with a bootable floppy
and suitable diagnostics on it for that drive. If not, you can get
the floppy image from your drive's website. Otherwise see 'man
badblocks'.
You might also have a deficient HDD controller, specially if
you've got a win-raid motherboard, with the fake raid disabled in
bios, but are usin the extra ide ports. Other possible causes are
faulty ram, or PSU. There's other more remote causes like bad caps
on the motherboard, to somethin simple like ide cable(s) that need
re-seating or replacing. IOW's the reason can be many and/or
varied, but boil down to user (including choices), or hardware.
