Adding drives

[balanga]

Is it possible with FreeNAS to get it working with one disk using UFS and change to multiple disks using ZFS as and when finances permit?

Not without having to recreate your pool. I think you can start with one disk using zfs then add another as a mirror. Then adding more mirrors from there.

Hopefully this will answer your basic questions:
