My pools with no redundancy is working very fine. Redundancy is better
but you can certainly run without.  You should do backups in all
cases.

I don't know about the CPU but 1Gb RAM on a home server works fine.
I even have a 256Mb debian in virtualbox on my server with 1Gb RAM.

Just turn X11 off. (/usr/dt/bin/dtconfig -d)

The installation have a higher RAM requirement than the installed
system as you can't have swap for the installation.

Before ZFS solaris has improved its RAM usage for every release.

Workstations are a different matter.
