Current theory is the horizon is no place special, other than if you
cross it, you're not coming back.

By current theory, nothing unusual, if you are in free fall.

You will see blue shifting and red shifting of the stars depending on
their position.

> Is it possible to fire your rockets and orbit the singularity?

It is possible to change your position in angle (\theta, \phi) but a
stable orbit is not possible. You will continue to approach the
singularity no matter what you do. The harder you try, the sooner you
get there.

> If you head away from the singularity, what happens?

You still move toward the singularity, in the same sense as if you turn
away from 2006, you will still get there.

Light you shine at the singularity gets there at the speed of light.
Light you shine away from the singularity gets there at the speed of
light. You are somewhere in the middle of those two extremes, and will
get to the singularity after the one and before the other.

> Will you 'bump your head' on the event horizon?

No, the horizon is (after all) moving away from you at the speed of
light. You can never regain it.

> And how does angular momentum affect any of this?

A rotating black hole drags space with it. Some claim the singularity is
drawn into a ring inside the black hole.

Google on "inside black hole" and you will find many write ups.
