I'm not sure about #1 and #3, but in the case of the likely future collision of our galaxy and Andromeda, we personally (or rather, our solar system) would have little to worry about.
There's some faint possibility that the planetary orbits could be disrupted if the Sun and another star get too close together during the mash-up, or that the Sun and its attendant planets could be ejected from the plane of the galaxy, or away from the galaxy entirely, due to gravitational interactions, but it's unlikely anything would have a direct impact on Earth itself.
