Yes you are.

That should do it. You may have to tweak the BIOS boot settings so it
boots from the new ad0. I don't have the hardware you do, so I can't
check that.

While you're adding new drives, I'd recommend adding a second swap
partition. Letting the kernel interleave paging across two drives
improves paging performance. If you're not paging, it doesn't matter.
