The relay is for powering up the TB6560's. The 1N4001 is for protecting the transistor driving the coil. Isn't this right?
And is the diode configuration in my v4 scheme okay to protect the MOSFETS? I see in the RAMPS and Sanguinololu that it could also be solved with a 10k resistor, which could be cheaper. Is that also sufficient?
