Absolutely.

Not so much - Thrust and Swing are game abstracts, not specific movements, and WM is adjusting the abstracts. Using a bow does not involve either a thrusting or swinging motion (it is more of a pull) and WM adds to the damage. I do not believe the description of WM explicitly defines the reason for this damage increase, which could either be the ability to place the shot in a more damaging location, or perhaps a strengthening of a few very specific muscle groups that is too narrow to justify even Striking ST.
