The book "Star Wars: Darth Plagueis" covers all that. It's EU, but it does a good job of explaining his origins and rise to power.
And they never did quite get around to spelling out the Story of how Palpatine came to be both a Senator and a Sith Lord and what his relationship with Shmi Skywalker was. He pretty heavily inferred that he had manipulated the force to create Anakin and used Shmi as a vessel to carry the child - how did this come to be? If true, that would, in essence, make Palpatine Anakin's father and Luke and Leia's grandfather, so very much part of the Skywalker family history.
I think there are enough lose ends in place to tell a new chapter...
