you should use the lines below, where it says "if you prefer to do this
manually...", it applies also to ext3. Do have a look at the manpages for
resize2fs and lvreduce, to find out the appropriate command line options for
your case.

Very generally, when you want to reduce a volume you first reduce the
filesystem, then reduce the volume; when you want to enlarge it, you first
enlarge the lvm volume, then you can expand the filesystem. The tools that
you use for shrinking/expanding the filesystem depend on the filesystem, and
are different for ext2/3/4, reiser, xfs... but you can usually look them up
easily on google. In your case, since you need to boot off a live distro,
make sure the live distro has all the tools you need installed and working,
which for you are resize2fs, lvreduce and lvextend.
