I've just finished reading the papers from Red Hat shortly before receiving
your e-mail. I guess I should have been a little more specific in that this
will be my home, desktop PC. I've currently got a thread going at Anandtech
discussing what filesystem for what purpose, partition sizes, etc. I've
gotten some very interesting responses but a few things keep coming back
around. As soon as I formulate more ideas I'm sure I'll be posting here to
see what SLUG thinks. I won't be using Linux (again) for quite some time
but I'm researching the hell out of things to make sure I have as many bases
covered before installing as possible. Essentially I'll have everything
laid out before downloading a distro.

These, though relatively old, may be helpful for your second question.

Since you mention using MP3s on the system I will assume that this is going
to
be a workstation and not an application specific server (read big database
server with multiple gigabit nics). In such a case I would wager that you
will not be able to discern any difference in tuning the ext3 journaling
beyond the defaults. But, you are probably also a tinkerer and would simply
like to try anyway.
This is another advantage of using ext3. You can try any and all the
performance setting that you wish without any problem because ext3 is simply
ext2 with journaling added. That means that you can add and remove
journaling
on your file system as simply as:
To add - mkfs -t ext2 -j
To remove - umount; edit /etc/fstab change ext3 to ext2; mount
see man mkfs and man mkfs.ext3 for confusing details.
