first question, would there be more rayleigh scattering on neon gas vs air?

im wondering if you have a tube of neon gas, and shine a laser through it, will the laser beam become visible? as opposed to shining a laser pointer around and only seeing the dot.

Going to depend on the parameters in the equation given there. Does Neon have larger or smaller average particle diameter compared to air? Does it have a larger or smaller index of refraction? If you find those, you'll be able to calculate the scattering intensity.
