I've set up systems like this (ssd sliced between root pool, and the
zil/l2arc for a bigger data pool).
But what I did was:
- install first to a conventional disk (whole-disk install)
- then get the ssd, and partition it from the command line, and
create the root pool on it
- move the active root to the ssd using beadm -p, and mucking around
with installgrub and bios boot order.
This indirect may not be necessary ... I didn't get the ssd until some
months after I got the original system.

What I'd recommend doing is to use fdisk to create a single whole-disk
partition, and then use *format* to create multiple slices within that
partition on the ssd
my convention was:
root pool on s0
zil on s3 (1GB is plenty for a home NAS..)
l2arc on s4

reserve cylinder 0 for boot; cylinders 1..N for root, ...
