Feedline routing and lightning surge protection Suggestions

I figured I would try and get as prepared as possible for the up coming spring T-storms. Yesterday I purchased 3 OPEK LP-350A lightning surge protectors. They are rated to 350w DC discharge at 50 ohm with less than 0.1 db insertion loss.
I have a 2m/70cm Diamond X50, a Homebrew dipole, and a Solarcon A99 10 meter vertical hooked up using LMR-400 coax to a box containing the surge protectors then routed inside my Shack(basement) to my rigs. I have the Lightning surge protectors mounted to a copper bar then grounded to a 9 ft copper rod in the ground with 8 ft of #8awg green insulated wire. I also have 9 foot of the same wire running from the grounding rod to a grounding bar inside my shack.

Am I on the right track with what I have done so far? I am very much open to constructive critiques and suggestions from the smarter people than me
Thanks, in advance!

The issue for most hams is properly bonding the electrical service entrance to the shack ground--for many hams--the most likely target for lightning is the overhead electrical wiring. And, if the most likely destination is the shack ground, because you did such a great job--you need to provide a good outside the house path between the two.

Tom Rauch W8JI has excellent pages on station grounding.
