You can run the commands:

tune2fs -O ^has_journal <dev>	# Clear journal flag
e2fsck <dev>			# Make sure everything is OK
parted <disk>			# Resize partition/filesystem
tune2fs -j <dev>		# Make a new journal

I'm surprised, however, that parted can't work with ext3.  As long as
the filesystem has been cleanly unmounted, it shouldn't need any extra
code except to recognize the COMPAT_HAS_JOURNAL flag.
