Yes, modules are primarilly about making your code easier to work on.  
However, you do want to preload your code during the server startup, which 
saves memory.

Check out the CGI::Application module on CPAN.  There are also some articles 
that have been written about it that explain the basics of separating the 
parts of your program into a model-view-controller design.

Packages are just collections of subroutines and data under a specific 
namespace.  If you can't imagine why this is beneficial, you might want to 
read a book about programming best practices, like Code Complete.
