By standart, you'll find your kernel in /boot directory, and kernel
modules in /lib/<kernel_version> directory.

Looking at the following:
============================================
[samuel@me ~]$ ls /lib/modules
2.6.11-1.1369_FC4  2.6.12-1.1398_FC4
[samuel@me ~]$ echo

[samuel@me ~]$ ls /boot
System.map-2.6.11-1.1369_FC4  grub                          vmlinuz-2.6.11-1.1369_FC4
System.map-2.6.12-1.1398_FC4  initrd-2.6.11-1.1369_FC4.img  vmlinuz-2.6.12-1.1398_FC4
config-2.6.11-1.1369_FC4      initrd-2.6.12-1.1398_FC4.img
config-2.6.12-1.1398_FC4      kernel.h
[samuel@me ~]$
============================================

I have two kernels:
2.6.12-1.1398_FC4  and 2.6.11-1.1369_FC4

The directories in /lib/modules are created when the kernel
is installed.

in /boot the important files are: System.map-$VERSION,
initrd-$VERSION.img   and  vmlinuz-$VERSION

As far as I know, config-$VERSION is only needed if you
want to know how the kernel was built... It should be possible
to copy it into the /usr/src/linux directory ( or wherever you're
building your kernel) and use it to config a build the same as
the kernel it's associated with.

And then one addition:   

initrd files includes system root for boot
process before real partition is mounted. initrd includes some
subset of modules from /lib/modules/{kernel-version}.  It is probably generated 
with command mkinitrd.
