speed of what?

Depends on the nature of the object you're talking about. An object on a track of some kind it would still suffer friction due to contact with the track.
The only resistance you would decrease would be that due to air resistance.
Light changes speed depending on the medium in which it travels, however it's sped IS constant within all media! Does that make sense?

Absolutely. About 300,000 kilometers a second. It is THE only true constant. All other constants bow in obeisance to this one. Space, time, mass, everything warps in order to make this constant stay constant. It's the emperor of constants.
For the speed of LIGHT, that is. Other speeds can vary almost up to the speed of light.

you question is not realy defined. Is the speed of what constant in a vacume under what conditions. If its accelerating then no, if its not accelerating then yes. If its acceleration is perpedicular to its motion then yes. and so forth

Inertia. Absent outside forces, sure. You do know the difference between speed and velocity, right?

Only the speed of light. Otherwise, there's nothing special; just no air pressure.

If no outside force acts on it, yes.
