That depends. I use ext3 on a 320MB drive in the 486 acting as the
router/firewall at my parents' house. I made it ext3 so that there is
no risk of corruption when the power fails.

Yes. In a nutshell :
run 'tune2fs -j /dev/<blah>'
edit /etc/fstab to say ext3 instead of ext2
unmount the partition
mount the partition as ext3.
It's a little nicer, but not necessary, to unmount the partition
before creating the journal.
Note that an ext3 partition is still a valid ext2 partition; thus an
ext2-aware kernel without ext3 support can still use the disk (albeit
without the journal).
I suggest reading some of the more detailed instructions on the web
that talk about tricks to let the ext3/ext2 mounting be automatic and
a little safer if you misconfigure something the first time around.
(namely declaring it ext3,ext2 and making an fsck symlink)
