Just the locations mentioned, and just the caps/components/pins (choose one for each area) at the approximate 22ohms reading relative to ground, just to give us a bit of a map and hone in on the area which represents the lowest vaue. As mentioned, maintain a consistent ground throughout and note the readings to the digit 
Yeah, pretty well
Can you highlight the caps in question?
Looks a little skewed, did you wick the IC and board prior to reballing? If you didn’t, don’t worry, you can address this later if it’s an issue.
