I gave that a shot once, but I found manual jail configuration to be better.

You shouldn't ^-^

Nope, FreeBSD doesn't need / want a /boot

A bit of overkill, but what the hell, you have the space

What exactly do you plan on running on the host?

Fine...

Huh? Refer to /usr above.

Fine again...

You'd be correct there :)
I'm sure you could fit everything on one disk... Jails are really small, it's
just your data that takes up space. If you could get everything in 250GB
(which i think you could easily) RAID 1 might be a nice thing to have
