Looking for fundamentals to get you ready as a self taught programmer is going about it in the wrong direction. Pick something you want to do and go do it. When you run into roadblocks try to figure out how to solve them and when you get too stuck then ask the question "what are the required fundamentals I'm missing in order to solve this problem".
You'll find you will rarely need to ask that question, just keep solving problems and learning what you need to know for that problem. You'll build good experience and though that experience you'll learn a lot.
