You can also put ground rods in horizontally in the case of rocky 'soil'.
Obviously go as deep as is practical but even if they're only a foot down
they will be helpful.

Would what be adequate? I'm not sure what you're referring to. You mean
more radials around the house or hooking everything together or...?
Copper strap is better than wire since it gives you more surface area for
earth contact so it's the preferred material for rocky soil.
Since you're in a high lightning area I would add some horizontal ground
rods to the house part of the system.
