Learning about kernels

Hey /prog/ thought this would be the place to ask. I want to learn from the ground up, low level programming. I thought the first to thing to know would be kernels, then assembly, thenC/C++/java/perl, and lastly scripting. Would I just need to wiki kernels to learn about them, or a book, some source on the web? Help!
