You should think twice before increasing the root parition size.  Yes, it is
tight, but generally you shouldn't be adding anything except symlinks and
mount points.  Root should be limited to the kernel and the basics needed for
single user mode operation/recovery.

To move/expand /usr, you will have to do a dump/restore to external media or
reinstall the system using the advanced installation path.  /var is usually
small enough to use disk as an intermediate media but tape is safer.

The only one you really need to do by booting the installation media is root.
If you have a second drive, it's easier to copy the root parition to the there
and diddle the drive nubmers, working the standalong environment involves
primitive operations like mknod and mkfs *after* you've probably blown away
your operating system.
