The manual still says use 4 stars, but after calculating the pointing file the top option for polar alignment says '3 stars'.
Which is it?
I am assuming that the star chosen for the polar alignment 'move' should be due South and at the same altitude as my latitude (52 degrees).
Is this still the best option?

For PA, I always use the 3 star same DEC option, as was recommended by Philipp some time ago.
The PA star should be as you describe. I get good results if the star is within 5 degrees from the meridian, and within 5 degrees of my latitude.
I usually don't bother to get better than ~1-2 arcmin on each axis. MLPT easily deals with that error.
