For the fundamentals: Objectivism: The Philosophy of Ayn Rand, by Leonard Peikoff, hands down.
Given what you've read, you might read that next, or you could read the rest of Rand's nonfiction. As I wrote in answer to the general question of "where to start":
You should pick a book according to whatever subject interests you most:
- For ethics, The Virtue of Selfishness
- For politics, Capitalism: The Unknown Ideal
- For epistemology, Introduction to Objectivist Epistemology
- For art, The Romantic Manifesto
All else being equal, I’d suggest reading them in the order they were published, which will help you follow Rand’s thinking as she developed it. The Ayn Rand Institute has a chronological list.
