    I know this is a dumb question, but I can't seem to find an answer to it anywhere. As an object's velocity approaches the speed of light, its mass increases, which should mean it would exert a greater gravitational force, but what about it's charge?

    Suppose the object is an electron. Will the charge still be 1.60217646 10-19 coulombs, or would a stationary observer experience it to be different?


    Some clocks are only right twice a day, but they are still right when they are right.

    This is not correct. Spacetime curvature is invarant.

    If relative motion were to "change" the gravitational field, any massive body would look ike a black holee to photon. It would be awfully dark around here.

    You do not directly sense charge. You sense the electromagnetic field associated with a charged particle. The electromagnetic field, as a 4-vector field is invariant. But the components that are described as "electric" or "magnetic" are dependent on the reference frame.
