Does your old P4 support 64-bit operation? Does it have 2GB RAM or
more? If not, then you might want to reconsider using ZFS. It's not
that it won't or can't be made to work given those limitations, but
you'll find it hard work to get it running stably and performing well.
UFS on the other hand will work just fine on 32bit systems and smaller
and older machines. (The limitation with UFS is a maximum 2TB
filesystem size, but I suspect this will not cause you any practical

Yes. You can run ZFS from a single drive. That's not where ZFS's
strengths really lie, but it's worthwhile as a learning exercise
certainly, and the zpool management stuff is cool in any case.

You plug the drive in and then run 'zpool import' with appropriate
flags to tell the system to investigate the new disk and discover any
ZFS related metadata on it. See zpool(1M) which has a long sequence on
the 'import' sub-command.
