See https://wiki.freebsd.org/RootOnZFS, particularly section 1.2.5, it 
will answer most of your questions. I have 2 machines running w/ FreeBSD 
9.3 on ZFS filesystems (unmirrored pools, not RAIDZ's, but it isn't 
supposed to make any difference) & everything works AOK. I followed 
section 1.2.5 religiously & all went well. Some of your specific 
questions depend on your mobo hardware, w/ a few more details (how many 
(SATA ? IDE ?) HDD slots on the mobo, for example) & the list could 
provide more help. What I *think* you want to do is quite feasible, you 
won't be winging it. $0.02, no more, no less. Have a good one.
