Tau Zero
For an imaginitive play on this idea the decades old SF novel by Poul Anderson - "Tau Zero" is fun.

Re: Why 3x10^8m/s?
I've never seen a calculation but I understand that when Maxwell formulated his famous electricity and magnetism equations and from them realized that they suggested a EM wave propagating and used them to calculate the velocity of propagation he got the answer of c. So it seems it has something to do with how E and M relate.

Don't know any more than that.

FTL
Actually, the expansion of the universe itself can be said to be faster than light.

Not in the sense that is being discussed. To say so would be messing up definitions badly. Velocity is through space.
