Answer 2

NO.  

Volcanoes from subduction zones have nothing to do with transform faults.  In fact transform faults are more likely to be found near the divergent plate boundaries than at subduction zones.   If you look at a map of the sea floor near the mid-ocean ridges (i.e., near the divergent boundaries) you will see where some faults exist perpendicular to the ridges -- these are transform faults.  You will see that the rock on one side of the transform fault moved a little faster than the other side -- this is what defines the transform fault and makes it different from a strike-slip fault.  Both sides are moving in the same direction, but one side is moving faster than the other.
