If you were floating around in space, and fired a gun

the gun wouldn't fire for one as rev night said

if it did fire then momentum would be conserved

(your mass) (times your speed backwards) = (Bullet's mass) (Bullet's speed forwards)

of course there's also rotation and such involved

There is a directional lamp attached to and pointing towards the front of a vehicle moving at 60mph. How fast is the light emanating from the lamp going?

The speed of light? Or the speed of light + 60mph, or other?

Speed of light + 60 mph + rotation of earth + rotation of earth around sun + rotation of galaxy

Why is he kidding? How do guns fire if not by combustion and rapid expansion of gasses?

Gunpowder contains its own oxidant in the form of potassium nitrate. Just like the Space Shuttle brings its own oxygen for the main engines. Did you think bullets burn just the air they contain or are breathing external air? :)
