Well, recovery might be more "interesting" if you have also
boot on ZFS :-)

I can't answer your second question, because I haven't any
experience with ZFS. By what you say, for me it'd be too
finnicky to put /boot and / on it. I'd keep your current
setup (unless you want to learn, and pay some price for it).

In the last case, I'd practice with recovery procedures
before Munrphy's Monster hits you.
