David,
Some random thoughts on your problems.
I've not used parted much, but have used Linux

other *nixes as a user.

Did you make /dev/sda5 too small? if this is /var or /tmp
you need a fair about of free space or you can get out-of-space
errors for the temporary files.

'Failed to cleanly unmount' ?
Parted needs the partitiions you are working to me unmounted.
Andrew - does Parted check for this ?

Use  'umount /dev/sda5'  to unmount minor 5, or boot using the
parted root disk (This is needed to if you wish to work on /, unless you have 
a spare partion which can be made / [Linux/BSD dual boot systems can be like 
this).

It may be possible that minor numbers changed, if this happend, edit your 
/etc/fstab to refelect the new minor numbers.

If you run parted within 'script', and post the entire session here, we can 
give more help on whats going wrong.

Possible instructions - take these with 1 Mol NaCl - they are of the top of 
my head. They will fail if there isn't enough free space on /dev/sda5

#First unmount the affected partions - 3 needs to be moved, 4 (an exteneded 
partion, containing 5 to 9) needs resized
#as the free space from 5 needs to moved to the end of 2
umount /dev/sda2 /dev/sda3  /dev/sda5

parted /dev/sda

#Half the size of  /dev/sda5
resize 5 1106 6106
#Move it to the end
move 5  6106 10260

#resize 4 (it contains 5 to 9)
resize 4 10260 17343

#move 3
move 3 1082 6082

#resize 2
resize 2 1106 6082

exit

#inspect fdisk -p and /etc/stab  to make sure that
#the minor drives haven't changed numbers/

#remount 2, 3, 5
mount /dev/sda2 /dev/sda3 /dev/sda5

As a sysadmin, what would you say to a luser
who came to and said.
'Emacs died saying "$Some vaguely remebered error" ' ?
