Ground wires on the firewall
I noticed two small ground cables hanging on my firewall in the engine compartment. They aren't hooked up to anything and I'm wondering what the heck they are.

The engine block is usually grounded to the firewall by a copper strap. Not sure about the other one.

Those ground straps are for radio noise suppression, one to each (left & right) valve cover bolt, along with the wire loom bracket.
Those straps aren't the main engine ground, that comes directly from the battery.

you can never have to many grounds.those straps are to ground the body to the subframe to complete the ground circuit.because the body is mounted on rubber.

Rick's/Ecklers has an engine compartment ground wire kit that has three small ground wires. I know that two go from the firewall to the valve covers. My question is where does the third one go?

Between the pass side subframe connection and subframe.
Looks like this:
