meteorites sucked in by the planets gravitational pull would slowly add to the mass I guess

no. The mass contained in a planet stays the same because matter cannot disappear, it can only change forms. There is no way to increase the mass of a planet.

They can if a lot of things from space fall on a planet. Usually there aren't enough things falling on planets to significantly add to their mass though.

Yes, the gravity of a planet will pull in space dust, meteors, asteroids, comets,etc. This is why you have to dig to get to dinosour bones. They have been covered up over time. Matter can be ejected from a planet if it is hit by something big enough but more is added than is ejected.
