About the only thing you left out is the interconnection between this new
ground rod and the existing house ground.

Sounds like you must live in Florida.  The best source of information is
the lightening lab at University of FL.

I've never read a good research backed paper on plastic v. metal conduit.
I bet it does matter.  I use iron pipe outdoors then after it gets indoors
switch to plastic.  Practical reasons.  The flexible plastic conduit is
just easier to use
