If you want to know what it _sounds_ like, do this (substitute your
kernel for vmlinuz-*)

cat /boot/vmlinuz-2.6.22-9-generic > /dev/audio

Open synaptic package manager, search for linux-source and install the
one you want to have a look at. It will install a compressed tar archive
in /usr/src/linux-source-<version>.tar.gz

Unpack it to /usr/src/linux-<version> and peek. Read the contents of the
Documentation directory!

Well, depends on what you are asking. The package is a single one, but
after unpacking, you will have a directory with a huge number of files.
However, once the kernel is compiled and packaged for installation, it
will end up as one package again (duh). When installed, it will consist
of the kernel proper in /boot and the modules (drivers) in /lib/modules.
However, a running kernel acts as one entity.

I think Wikipedia gives a really nice introduction
