The system sounds depends on esd as you've found out. I've never had
it work correctly 100% of the time, so I can't say why it doesn't work
for some actions or doesn't shutdown. However, I think it should use
ALSA. In my experience, there are only a handful of programs that
still demand OSS. The main one (for me) was the older Adobe Flash
plugin, but the new one can use ALSA, IIRC.
My guess it that GNOME is currently configured to use OSS through
libgnome. What's the output of this command?
$ gconftool-2 -g /desktop/gnome/sound/default_mixer_device
For me, it's "alsamixer:hw:0". One thing you may not have built at
first, but is very nice, is the mixer applet from gnome-applets. This
requires gstreamer base plugins. This gives you a much nicer view of
your sound streams. This doesn't control esd, though.

Often the way this is done is to make the the snd-pcm module pull in
the snd-pcm-oss module in modprobe.conf. This is explained in LFS:

You need more fonts. See the Xft section here:
http://www.linuxfromscratch.org/blfs/view/svn/x/x-setup.html#fonts
Installing FreeFont should give you (ugly) characters for nearly
everything you find.

It's a weak attempt at Gnome integration in Firefox. It tries to set
the proper gconf key to make it the default browser, but it's setting
the wrong key. Just turn that dialog off and set firefox as the
default in the Preferences/Preferred Applications menu. I believe this
should be fixed for Firefox 3, but not sure.
It's actually a little worse, too, because saying Yes to that dialog
makes firefox set itself as the default URL handler for nearly all URL
types. So, now firefox is your preferred FTP handler, too.
Did any of that help?
