You should if you are using the kernel that matches the rootfs you picked. In 
the terminal run:
	uname -r
This will tell you the kernel release. You should find a matching directory 
under /lib/modules.

Modules in general are for optional things that you don't want compiled into 
the kernel. They are often drivers.

The modules-version.tar.gz contains an archive of the modules for the kernel 
of the same version. This is needed by people who want to use a different 
kernel to the one originally used for the root image.

Yes. The image is built for a particular kernel, and includes the modules for 
that kernel.

See answers above.

The wiki assumes some basic level of linux knowledge. I guess we should 
include links to some basic linux primers in the 'getting started' page.
