This means that position and velocity are not based relative to other objects, but to the actual fabric of existence.Which would mean that there is some base speed of zero that is independant of every object in the universe. So for the limitation of the speed of light to exist, wouldn't all speed have to be set relative to this reference? So then an object travelling at .99C away from Earth could be travelling at 1.1C relative to the actual fabric of space.

There is no such thing as a fabric of space (well it is assumed). Relativity assumes that absoloute time and absoloute space DO NOT exist. This is in comparison to Newtonian which suggests there is such a concept. However Newtonian can't explain the bending of light and acceleration close to c. So as before you muct have an inertial (non accelerating) frame of reference to take measurements from.

To put that idea in a little easier to follow form, let's say that space is the ground, reaching out to infinity, and all the planets, stars, etc. are just cars driving in every which direction over the ground. Wouldn't the speed of the photon be calculated in reference to a point on the ground instead of one of the moving vehicles?
I hope that made it a little easier to understand.
About the black hole thing, I didn't think of that and it seems to make sense.

Looking at this now it is just the same question as above. The ground ('space') you refer to is not inertial so can not be taken as a frame of reference. Alternatively if you are referring to some type of Ether I believe many experiments have looked for this and all have failed.
