I'm not any sort of physicist. I barely passed my high school class, but from what I read general relativity precludes anything with mass from traveling faster than the speed of light. (Spaceships and their occupants generally have mass.)
It sure does, to be specific it states that information (matter) cannot traverse two points faster than the speed of light, however spacetime is not matter and is masseless, that means that at the very least spacetime expands at the speed of light, however we have reasons for suspecting it was faster.
Effectively inflation was proposed to solve many observational discrepancies with the standard big-bang theory, namely the horizon problem, flatness problem etc.
The visible universe is 19 billion lightyears across, if expansion happened at the speed of light it should only be 13.7 billion lightyears across.
Spacetime can move away from it's self (from the equidistant point of two edges) faster than the speed of light, provided that no two ends of the expansion are in communication with each other (can "see" each other).
If you want to fry your brain i suggest you (attempt) to read the following:
