Both of these may be found in the dictionary:
snap (v): 1.2 [with complement or adverbial] Move or alter with a brisk movement and typically a sharp sound.
bound (v): 1.1 (of an object) rebound from a surface.
So "to snap forward" means to move sharply or suddenly, in the "forward" direction. If someone is struck in the chest, it's not unusual for their arms to "snap forward" as their torso moves backwards.
"Bound off" is another way to say "rebound" or "bounce" off of something. In this case Zouga struck the tabletop but bounced off with little damage from the impact.
