Gravitational effects of nearby stars are unlikely to be felt at all. The gravitational effects of the galaxy as a whole will be tremendous, but they would barely differ from one side of the solar system to the other. The solar system won't notice any of them as a result. Aside from ejecting the entire system, or grabbing it, Andromeda will hardly affect a single orbit in it.
Eventually it will but on a much larger timescale than I was originally talking about...but still in a finite timescale before the end of the universe. Its a cumulative effect.

We should definitely see solar system effects through radiation and such in the merged galaxy, as I said our solar system won't be part of it. Humanity as a galactic entity will likely be though.
These changes will take place on such a slow and immense timeline that no one will even notice except in an abstract way. Even the ejection of our solar system would take hundreds of thousands of years.

This is like amoeba in a pond during the coming of winter. The time scale is just so off that each generation will just consider the conditions during their life time to be status quo.
Well the overall timescale we were discussing was to survivng the end of the universe, or not surviving it-a topic which I didn't bring up--so that doesn't seem to be a timescale that's out of the question.
