You may want to download the following graphical overview of the
UFS/FFS filesystem that was made by Poul-Henning Kamp earlier
this year, it's very useful:

http://phk.freebsd.dk/misc/ufs.pdf

If you want to print it out you'll need 18 sheets of paper.

You may also want to use something like doxygen (devel/doxygen in the
ports tree) to generate source code graphs and make browsing through
source code easier. Another resource that you may find helpful is
Robert Watson's FXR site:
