hmm...you should consider whether or not you want to uphold the <9 char filenames. It used to be an issue some years ago...But if your package consists of modules ONLY, then the preferred way is tar.gz the directory whose name should be the name of the module. Inside the directory are the modules including the dirname.pm. But I'm assuming your're interested more in a large app that you want to throw together for the user. In that case, you'll have to consider whether or not you want to throw your modules into the /perl/lib dir wherever it is. (That is easily obtainable by using the first dirname in the @INC or some %Config def.) Then, you should establish some system of installation. Where should the executable (main script) be? A possibly useful module for larger projects will be ExtUtils::MakeMaker. guess what it does...
