I also have been with the understanding that equipment in the shack should be 
star grounded.  Each piece of equipment grounded to a single point.  

So we should now bond each box to each other using a wide flat strap or copper 
mesh (shield copper) from RG8 or equivalent, then take that total bonding to a 
station ground such as a ground stake outside  using large solid copper wire or 
to copper water piping inside the house with the braid or strapping and 
bypassing around the water meter, for lightning protection?

I have mine connected to both the copper water pipe (to street side of the 
meter) and solid copper to a multiple ground rod system around my tower and 
another connected ground rod outside the shack window, all are connected
