Tectonic activity is concentrated at plate margins, because that is where the collision (destructive plate boundaries) or division (constructive plate margins) occurs. This is the place where the two plates hit each other or move apart, causing things like earthquakes, tsunamis, volcanoes and fold mountains. The impact, or the force, of the plates is biggest at the plate boundaries.
Convergent boundaries can form between two oceanic plates, between one oceanic plate and one continental plate, or between two continental plates.

collision is when two plates collide conservative is when two plates rub together
The MARGINS project has now been replaced with GeoPRISIMS. The project's work was studying the behavior of the earth's crust at the margins of the continental plates. It's work continues as part of GeoPRISMS
Constructive plate margins are when two plates move away from each other, creating more ocean floor.

Continental crust is thicker and less dense while oceanic crust is thinner and more dense, so essentially continental crust takes a higher position than oceanic crust. When oceanic and continental plates collide, oceanic plates slide underneath continental plates(if this makes what I said any clearer).
Yes, several of the plates have their margins under the oceans. The Pacific Plate would be the plate with the largest area under the seas.
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.
