Both jazz pickups are going to be wired to a single volume pot, which means both pickups will always be at the same level. The pot will be a pull pot for switching the jazz pickups to series. From the volume pot, the signal will go into the preamp.
The MM will have its own volume pot, which won't be a pull pot, but the MM pickup will be wired in series constantly. The signal will go from the volume pot to the preamp.

Both the jazz coils and the wiring for the coils in the MM humbucker are in parallel in the original instruments. If you want series, that's up to you but as I mentioned above, you'll have to reset your input gain on the amp/effects board every time you switch between parallel and series. It will drive soundmen NUTS. You also won't get the characteristic MM sound if the coils in the humbucker are in series.
You will need to be clear about the effects of polarity when you mix the humbucker and the single coils. The jazz scoop comes from the single coils being reverse wound and reverse polarity in comparison to one another. I have no idea what will happen when you mix them with the humbucker.
