It sounds like you're looking in the right place to get the kernel source.
It gets installed in /usr/src/redhat/.  If you type:

ls /usr/src/redhat/SOURCES | grep -v patch

you'll see that there is a linux-2.6.xx.tar.bz2 kernel. All those patches
are simply the redhat changes to the vanilla kernel. The rpmbuild process
will take care of all that for you.
