about 1. is ok, but when the mouse on second chart,the first chart is not work.
You can try triggering event for the first chart based on the event fired in the second chart. That should work fine in your case.
about 2. my mean is to calculate the difference by selecting the two dataPoints.
Please take a look at this jsfiddle.
