Two things that came to mind when watching AOTC: At Shmi's funeral, we see two other gravestones outside the Lars homestead: a large one and a small one. Has there ever been an explanation about who these belonged to? Whatever happened to Mas Amedda, anyway? The film implies (and ROTS makes pretty explicit) that he is very closely involved in Palpatine's plans, possibly even to the point of knowing his true identity. But even in the EU, he seems to just disappear a few years into the Empire. Was an explanation ever given about this?
