What sources do you recommend for me?

I want to learn how to use Linux well so I can finally leave Windows behind. But I would like to truly master the entire OS, not just the superficial stuff, and not just copy and paste the steps when I run into a problem. I would start with Ubuntu and then scale up to more advanced distributions like Arch Linux, as I aspire to customize the OS—in fact, almost without a graphical interface. If I ever want to modify something in the OS, I want to be able to do it, to be able to create a tool for it, and to contribute to the community by coding. Can you give me sources for different levels? Basic, intermediate, and advanced.
