I did option 6. That took the Verizon router out of the picture as all it does now is handle the STB's guide, VOD and onscreen caller id. I stuck it under the stairs where it's out of the way. Was a simple change only took about 20 minutes.
If you did it that way you don't need the moca adapters as the Verizon subnet is all by itself on the coax segment.
