My idea is for the whole system to run off a Live CD, but I'm quite
lost how to start the X windowing system, then the web browser and
then automatically shutdown the whole system after quitting web
browser.
As for the browser starting when X is started, this would do:
echo exec firefox ~/.xinitrc
and with sth like
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin/:/usr/local/bin \
sudo -u display -H /usr/X11R6/bin/startx /var/log/Xdisplay 21
/dev/null
in rc.local you even get it automagically on bootup.
When you quit Firefox, X will terminate, too. Your other requirements
are a bit trickier though.
not really - if you start X in rc.local and don't background it just
poot halt -p as last command in rc.local.

Here's the set of files I used for a year or so to create and operate
'public' computers that only ran Firefox. The clic.sh file, when run
from a fresh install, turned the machine into such a dedicated device
by installing the files provided and editing standard installed
config files. i.e. have all the files on a USB stick or something,
and run clic.sh from that directory.
The pf.conf is to ensure no 'internal' machines (which were all on
non-routable addresses) could be accessed. The rc.local magic was
to allow access to the default gateway, obviously an internal
address. :-).
fvwm so the users could close popup windows.
crontab to shut it down everynight at closing time.
Firefox 3.5 because they needed to run Java apps, and the later
plugin did not (and still doesn't I think) work.
The file missing (firefox35.tgz) I created by starting up firefox once
as 'client' and tar'ing up the resulting .mozilla directory. This was to
ensure meant there was a 'clean' firefox everytime it started up.
It was moderately annoying to have to boot to single user and fiddle with
/etc/ttys to do any maintenance, but I never got around to allowing
remote access.
No great innovation, just a lot of trial and error starting with henning's
advice, a lot googling and reading X Power Tools.
And haven't run it in a year or so, so ymmv.
You might also want to investigate xxxterm and its 'kiosk' mode.
