ad 4. I was "half-holding" the shutter button for atleast 2 or 3 seconds before I fully pressed it to start the sequence. Not sure if using the AF-ON back button would improve the results?

Yes, removing the focus from the shutter and using just AF-ON will significantly improve the focusing. It take a while to get use to using the thumb instead o the index, but you can control the when of the focus which you can't with the index/shutter.

The photos that you are showing are the perfect situation for using the 19 points AF in AI Servo. One big large subject moving and everything else staying static.
