For full range measurements, you'll require the ECM8000, but for simple home use for subwoofers, the Radio Shack meter would be fine.

You can certainly use the firewire to the PC (as long as it isn't a MAC), but you must use analog for the mic and connection to the receiver. There would be no way to calibrate it otherwise.
