G'day Adam,
First question: dunno, it always seems to get the image scale right for me. 3.0x seems about the right image scale without the reducer. I wonder if that's a coincidence? Have you set the correct (reduced) focal length in Maxim?
Second question: on my mount a sync is a sync no matter where you do it (unless you tick the box that says to convert a software sync to a recalibrate!) The last sync is the only one that is remembered.
Third question: you should be able to overlay an image on the observatory zoom window now and calibrate to use auto center.
Cheers,
Rick.
