Is that saying it is scsi2 or or what is that telling me?
It's telling you the device is /dev/sda4

Do I add /dev/sda4 /mnt/zip vfat defaults,noauto,users,noatime,unmask=000 0 0 to my fstab?
Entries in fstab are mainly for giving permissions and parameters to mount devices, add the line to give users the right to use it.

When i mount /dev/sda4 /mnt/zip
mount: /dev/sda4 is not a valid block device
Is this because no entry in fstab?
Try first to mount it as root and specifying the filesystem if it's not detected: mount -t vfat /dev/sda4 /mnt/zip
You can also check the filesystem used on the ZIP drive with: fdisk -l
