As well, in regards to the Lorentz contraction theory, does it really take 20 years for light to travel 20 light years if the contraction occurs and photons have mass, and so on?

The Lorentz Transformation Equations are not theory.
Photons do not have mass. They do have momentum (p=hf).
Yes light bends around mass. This was one of the original cases that proved General Relativity.
It takes the light 20 years, from our perspective, to get here.
Don't worry, my head hurts too.
