Well, action and reaction pair always act on DIFFERENT bodies, so it CAN NOT be compensated. For example, you pushes SOMEONE (in vacuum, or in weightlessness, or wherever) with the force F, and due to reaction he exertes force on YOU equal -F, so you move away from each other (repell).

So gravitational attraction accelerates hydrogen, and it is warmer and warmer until nuclear fusion starts.

Nothing as you describes.

Binary of ALL sizes waltz with each other: because they exert exactly equal forces on each other, then from F1=-F2, or m1a1=-m2a2, follows ratio of accelerations (and thus, velocities and positions): a1/a2=-m2/m1, so the heavier the star, the smaller the "waltz".
