Good question. Clearly black holes as a whole can be affected by
gravity in the normal way - they follow geodesics. I'm not sure how
they are affected by, say, tidal force.

I think that angular momentum is contained and consevered inside the
event horizon. The horizon itself doesn't have it, though it's shape
is determined by the angular momentum at the time of formation.
