Your grounding plan sounds fine, *if* and only if you connect that
separate ground rod to the utility entrance ground rod using a #6 or #4
copper wire - that wire should be buried several inches and run outside
your dwelling foundation.
That connection is a NEC requirement and is necessary for safety. All
ground rods *must* be connected together unless they are more than 100
feet apart.
You cannot create an RF ground by connecting to a ground rod. It is
only for AC safety and a measure of lightning protection.
OCF antennas can be difficult to tame for RF in the shack. Use of a
very good quality common mode choke at the feedpoint (in addition to the
4:1 balun) may help.

The plan I'm thinking of so far.
1. Run an 8 gauge dedicated power feeder from my main panel (on the
opposite side of the house) to the shack with a 20A breaker. The 8Ga is to
lower ground losses.
2. Install a ground rod outside my shack and run a heavy gauge to the
shack to bond with the dedicated power line ground.
3. Ground all gear in the shack to the dedicated power ground.
4. ?? maybe do a run of 14-2 romex with all three leads bonded together up
to the mast, install a mast antenna switch and ground it with the 14-2.
