Thats exactly what you should see (voltages a bit high on the Dir, but as you say probably meter) so the BOB is OK, the Port is OK, only really leaves the drives.
Personally I would hook up the 5V but thats me, docs are not great so not sure exactly what they mean, wiring shows theres nothing connected but docs seem to suggest there should be.
Dont think you would do damage but not an expert so cant say for sure.
If you hang on 10 mins I will go look at the coil winder and see what I have there, its got similar drives too yours.
