For he first part, and knowing quite abit on Blackholes, (I did a thesis) nothing can go faster than the speed of light. So therefore a black hole sucks up everything. A ship can stop itself (in theory) as it comes from a internal source. The only way a external source could stop the ship if there was a obect in the way in which the ship would be destroyed or if a ship could simulate the gravity of a black hole, which if it did that would suck it self in.
