What's the difference between the Higgs boson and 
the graviton?

Google hasn't given me an explanation that I find completely satisfactory.

Basically, what I understand is, the Higgs boson gives particles its mass, whereas the graviton is the mediator of the gravitational force.

If this is accurate, then...

1) Why is there so much more focus on finding the Higgs boson when compared to the graviton?

2) Is their existence compatible with one another, or do they stem from competing theories?

3) Why does there need to be a boson to "give" particles mass, when there isn't a boson that "gives" particles charge or strong-forceness or weak-forceness?

It might help to realize that mass and gravity are distinct things: in a universe with no gravity, objects could still have mass. The basic property of mass is that of inertia; that is, the more massive an object, the harder it is to push or pull on it to change its direction or speed. In our universe, mass has the *additional* property that it creates a gravitational field that attracts other masses, but as far as we know that is not an "inevitable" property of mass like inertia is. So, on a space station, it is much easier to play catch with a baseball than a bowling ball, even though there is no apparent gravity.

So, knowing that inertia and gravity are distinct, it is easy to see the different roles of the Higgs and the graviton. The Higgs gives particles mass (inertia) which would exist even if there was no gravity. The graviton is the hypothetical particle that carries the gravitational interaction between massive particles. These "jobs" are completely distinct from each other, so in answer to your second question, those two particles are not part of competing theories, they could both exist.
