In theory; raidz1/2/3 are listed in the GRUB manual[1], and later[2] has an example FreeBSD ZFS menuentry. The Arch Wiki also has some information on ZFS[3] that may prove useful. > 2) What do I need to do after creating ZFS volumes to perform a base install > onto those filesystems.

You might be able to boot d-i, skip partitioning and install to the root. Alternatively you could install to a small ext4 partition and then copy it to the ZFS volume(s). Otherwise you'll need to do a manual debootstrap and whatever other required configuration steps d-i performs.
