I had someone format an entire hard drive the other week - not fun!
Luckily, it was a FAT partition, and I threw together possibly the worst
program I've ever written to get everything back.
I strongly suggest you find a spare drive somewhere and take the extra
time to copy the _ENTIRE_ device to an image on the spare drive, and
mount it through the loopback device:
# cp /dev/hda /mnt/spare/working.copy
# mount -oloop /mnt/spare/working.copy /mnt/screwed

That way, each time you complete screw up the file system (and you will),
you can copy it all from the original drive and start again.

If the ext2fs tools won't work with a disc image, you could copy the
filesystem to the spare drive and then edit it in place, recopying it from
the backup each time, I suppose.
