The /boot directory must not be encrypted, so you need to put that on a
separate slice.

As for the rest, maybe the following thread will help you;
http://lists.freebsd.org/pipermail/freebsd-geom/2006-July/001401.html

The thing is that sysinstall doesn't support creating encrypted disks,
so during install, you'd have to initialize and mount the encrypted
slices manually, and then resume sysinstall.

Personally, I wouldn't bother encrypting anything but your own data,
i.e. /home. And for backup purposes it's better to make a seperate slice
for that anyway. Disk encryption is only usefull when your disk is
stolen; as long as the disk is mounted, the data is readable (if
permissions allow) anyway.

If your /home is already a separate slice, back up your data, unmount
/home and encrypt it according to geli(8). Mount your encrypted drive
and restore your backup.

A good idea might be to create a virtual machine with e.g. qemu, and
practice on that before you screw up anything important. :-)
