The body diodes block internal flow.

I don't see any point to the 50 Ohm resistor. It will slow the speed with which power 'comes up' at power up. But, is there a benefit to that?

That is just in case you are using a more powerful driver than speced. The resistor can be eliminated if you are using a standard FET driver

Once the 'forward' MOSFET is gotten rid of, the zener protection needs to be from gate to source of the 'backwards' MOSFET.

The "protection" is just keeping the driver from providing too much voltage to the mosfets. No more
