I suggest you use qtparted. Basically you need to:
1. Resize /
2. Move the swap volume back so it is adjacent to / (as it is swap, you could just
run swapoff, delete the volume, and then recreate it.)
3. Reduce the physical volume size
I don't know if qtparted can do step 3 but it can do steps 1 and 2, I think.

/dev/hda5 contains a label called /boot. That means if you move /boot to a different
partition, you don't have to change your fstab, which is useful, but rarely.
However, if you ever insert another Linux-formatted hard drive in your system,
from a different computer, it can cause the OS to become very confused as it cannot
determine which "/boot"-labelled partition to use! That is the disadvantage of
