Being a newbie myself, I think the best way to understand journalling would be to understand first its structure and then read jbd/jbd2 codepath. And to understand structure easiest thing is to read the code of debugfs (which comes with e2fsprogs) or if you are comfortable with C++ (unlike me :( ), read the source code of ext3grep.
