Instead of asking what files do you need to understand. You should ask yourself what subsystem do you want to learn? Focus on functionality and browse the code to understand. As others pointed before there are lots of good books that will give you a high overview of the kernel. The first book that I recommend reading is Linux kernel development by Robert Love, but only if you have already read a book on operating system concepts. The best book for me is Andrew Tanenbaum's Modern Operating Systems.
