The only difference between an ext2 filesystem and ext3 is that the ext3
has a journal. Turn off the journal and you have an ext2 filesystem. The
tune2fs manpage tells you how to do that. If you don't trust that on one
of your live filesystems, experiment by creating a new filesystem (you
don't have to have a free disk partition to do this, you can do it with
a filesystem in a file) and make sure you know what you are doing before
doing it for real. After you finish resizing, you can turn the journal
back on and convert back to ext3.

Note that you can only turn the journal off when the filesystem is not
mounted or mounted read-only, so you will have to do that using a rescue
CD or some such.
