Is the flattened Event Horizon illustration correct?
It occurs to me that is black hole is going to suck things in, the rubber sheet illustration of a black hole has to be incorrect because in fact the "disk" of the event horizon should be a sphere and matter should be swirling all around a black hole and not in a neat "down the drain" sort of illustration. Ir am I wrong?
Also, if nothing can escape a black hole, how do we know they rotate at all?

The 'flat picture' is a 2D illustration, because the (correct) 3D picture you describe is very, very hard to draw. (Try it!) It does aptly illustrate what is going on, though. The rotation of a black hole would have measurable gravitational effect, although I can't say I know of these being measured. If you believe in the conservation of angular momentum, however, you can see why they must be able to rotate.

Christop supplied a very good answer. As for rotation -- most black holes are what's left of super-massive stars. Those stars rotated and due to the Law of Conservation of Momentum, the black hole must retain that rotation.

The rubber sheet is an attempt to illustrate a four dimensional effect using a 2 dimensional simile.
We know it is imperfect but till they invent 4 dimensional paper?

its called frame-dragging of a heavy mass-and yes it is correct ,proven by the GRAVITY PROBE B
