Because you are running on DOS partitions, then you probably want to use
GNU parted (which uses the ext2resize code).  It will also handle the
needed changes to the partition table, which ext2resize will not.  If
you are using something like LVM, then it is a lot easier.

Maybe yes, maybe no.  If you are able to directly log in as root, then you
will be able to unmount /home (you may need to change /etc/ssh/sshd_config
to allow direct root login).

You need to shut down all unnecessary services to make /var unmountable.
You can use "lsof" to see which processes have files open in /var.

Good luck.
