Is this enough protection? Anything else I should do? Lightning is pretty uncommon where I live, but I really don't want an incident frying all my lab equipment.

Agghh!  DON'T tie the lightning ground to the house wiring.  If you do, a lightning strike will likely blow out every electronic device in the house.  You want to send lightning current into the ground away from the house wiring.

That's no longer the plan. I'm planning to connect it to the thick wire connecting the electrical panel to the grounding rod with a ground clamp. This will all be on the outside of the house.
