does he have to exert any force to throw a bolling ball if the ball is also weightless? I can't get this. Any guesses?

Tony is right: F=ma
Notice also that the force you apply on the ball will also affect you (the astronaut). Thus, the ball will head in one direction and you will head in the other.

A ball will 'boll' if an arm's force is exerted on it, even in space.

If you're weightless, are you also massless? What about the bowling ball? Is it massless?
Remember, F = ma. If you want to accelerate a mass, then m and a are both positive. F better be, too.

yes he does, technically no one is ever massless. astronauts in orbit are in a state of continual freefall giving them the feeling of weghtlessness.
the bowling ball, and the astronaut himself would still have inertia and momentum. subsequently you would need to exert force to throw a bowling ball still.
