It is not possible, and to see why it is likely easiest to take the perspective of an observer at a fixed distance from the black hole. ( The guy who holds on one end of the wire.) From his perspective, he sees that the wire is lowered towards the event horizon, but the tip of the wire is redshifted and moves slower and slower the closer it comes to the event horizon. This is because the light reflected by the tip of the wire needs more and more time to reach the observer. And in the end, the observer will never see the wire actually reaching the event horizon. And since signals in the wire can not move faster than the speed of light, the origin of any signal through the wire is further away from the event horizon than the perceived position of the tip of the wire. About your other questions ( and being a bit sloppy with my definitions): Inside the black hole the radial coordinate becomes timelike, that means the singularity is in the future of every particle which has fallen into the black hole. And you can not orbit around the singularity any more than you can orbit around next Thursday.
