Regarding the 2nd question...

As /usr/src contains the source of building the userland and kernel, if 
you can always man <something that is interesting>.

You can also do a man hier, but it will present a description of each 
directory content like the Developers Handbook (although more verbose).

There are also the Makefile and the actual source.
