options (from most to least ambitious):

1) switch over to using LVM2, where you can resize at will

2) combination of parted and resize2fs

3) don't really resize.  just cheat and move stuff using symlinks if 
you just want to fix the problem for now with the least effort

p.s.  your root partition is a little on the large side as well.
