This is a mythconception (ugh, I don't like that word either). We don't know if Gravity is a pull or a push. We deduce it's a pull because of our inability to jump off the earth. Gravity could just as easily be space pushing us to the ground. We don't yet know what space is either.

Force is a vector, so does the push/pull matter at all beside the direction the force is acting?

Interesting. But we do know that the mass of an object creates more gravity... So in relation to the object in question it would be "pull" to the object. I see what you're getting at but for simplicity I think "pull" makes sense.
This may be completely wrong, but I think of gravity as a trampoline and balls placed on the trampoline. If I stand in the center of the trampoline, the objects will fall to me. The more weight I have, the faster or harder the fall.
