You can stick with your own kernel if you want.  No reason to change if
it works for you.

nvidia-kernel-common provides some startup scripts and such.
nvidia-kernel-source provides the kernel driver code that has to be
compiled for each kernel you want to run it with.  module-assistant
(m-a) is a great tool for compiling that against your kernel sources.
nvidia-glx is the actual X driver that talks to the kernel modules.

I am tempted personally to add this to a startup script:
modprobe nvidia || m-a -t a-i nvidia && modprobe nvidia

That should take care of rebuilding the nvidia driver when the kernel

nvidia-glx is the binary X driver.  nvidia-kernel-source contains the
kernel hooks code and the binary parts for the kernel.

Hmm, no clue about that dir.  Never had to look at it.

You can simple grab the source package from i386 and build it on amd64.
Works just fine.  nvidia being non-free and amd64 being still unofficial
and such means a few things don't get auto built.
