Allthough this may not be the answer you've expected, you can
put /var and /home onto the same partition (the 235 GB left).
Put /dev/ad0s1g in /etc/fstab as /home, create /home/var and
put a symlink /var@ -> home/var. This does not create the "over-
head" a LVM would need.

As it has been mentioned before, ZFS is much more professional
of course. You can add storage to /var or /home without needing
to move any content to a new disk. ZFS is part of the base system.

Yes, FreeBSD brings vinum LVM with the base system.

I don't think so, but there are tools in sysutils/e2fsprogs that
might help you: "Set of utilities and library to manipulate an
ext2, ext3 or ext4 filesystem."
