Keep in mind that all the cliches about black holes are about non-rotating black holes, which don't exist in reality. In reality, a spinning black hole has a ring singularity, not a point, and behaves much weirder and even less intuitively than the hypothetical non-rotating counterpart as it smears out spacetime into taffy.
Is it theoretically possible to shoot something through the ring? Or does the even horizon completely envelop it?
the event horizon is effectively a sphere, like inflating a donut-shaped balloon (that can't pop). Eventually the middle hole is going to close like a sphincter (enjoy that imagery) and the whole thing will approach the shape of a sphere because that's what anything becomes when you inflate it hugely.
