PartitionMagic 6 should work fine. YMMV.

Nothing beats backups. ;-) Although I have no experience resizing ext2
partitions mounted rw(or ro), from `apt-cache search ext2|grep resize' :

ext2resize - an ext2 filesystem resizer

Versions available for all three flavors.

IBM DeveloperWorks has some good articles by Gentoo's Daniel Robbins on
the different journaling fs available for 2.4. I can vouch for a
painless (and pretty much instant) conversion from ext2 -> ext3.
