Hi Sam,
Here are a few answers:
1) Yes, you get more flexibility there, and repositioning the mid mic layer is possible, but rather tedious. Mid mic position is always the same (also for bigger instruments / sections like Timpani).
2) Yes, if you apply the Library Update for SY perc I, this feature will be available for Timpani and Concert Toms.
3) These new options have been implemented pretty straight-ahead in the libraries. Let's see how much demand there is for a walkthrough.
Best,
Paul
