if gravitons carry gravitational force & photons carry electromagnetic force how can the gravitational pull of a black hole be sensed if neither photons nor gravitons can escape IT?
How could spacetime warp around it without getting the information from gravitons that a massive body exists next to it?

The key is in your first word: IF.
Modern theories found two ways around the problem:
Gravitation is the result of the "curvature" of space-time imposed by the presence of mass (without the need to resort to gravitons), and
The "information" that space-time needs (to determine the "required" curvature) comes from the event horizon, not from the black hole itself. This approach is consistent with the latest thoughts that all information is NOT lost about matter than enters inside the event horizon, but that some part of it is "imprinted" on the event horizon.
The words I used are for my own benefit. Even though I am trying to understand how this works, I am far from understanding it fully...

Gravitons carry the gravity. If gravity is understood in Einstein's terms, spacetime is curved around the object with high gravity like a star or black hole. Gravity has to understood in either one terms or another:either in terms of gravitons or curvature of spacetime. Light is affected by gravity as it displays the smallest possible mass[if you can call it mass]. So light does not escape from a black hole.

gravitation is something that can hold extrememly large bodies, like skyscrapers in tact. In fact a building of one depends in big part on the force of gravity. If you interfere into the field that supports an object, the field will dissolve leaving the particles all to themselves untill the next near by pull. Human movement on the ground is all gravitation.

We know a black hole is there because of the effect on the surrounding stars and from energy that is generated out side of the event horizon. I will pull up a link I found this early morning. Good lecture on "Frame dragging" and event horizons, and discussion by the first discoverer of a black hole. Also a lot of other very good clips on science/ space matters.

You have to think of a black hole as a vaccum cleaner sucking in anything in the vacinity and getting more suctions from more matter thus sucking in things further out as it grows. Eventually it sucks in all the mass of the universe, becoming a singularity.

I think you just discovered a flaw in Hawking's theory, or Einstein, or whatever...so i dont think anyone can answer that...
