Or would it be better to just make the tomato base in advance and braise the squid before dinner?

No you cannot. You will wind up with rubber nuggets
Sorry, I completely disagree with the below poster. You absolutely can pre-braise squid the night before. As long as the cooking time is long, the squid will still be tender. I've done it many times, promise.
