No, that information is outdated.
The *.symbols files in /boot/kernel are required, "stuff in /usr/obj" is not.
You start debugging by
kgdb /boot/kernel/kernel /var/crash/vmcore.0
or whatever are the proper paths.

BTW, this section is also obsolete:
http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-kld.html
Modules/their symbols are loaded automatically in the recent versions of FreeBSD.
