I'm also planning to release a perl-based application and have had similar questions.

I've chosen to follow the example of Andy Lester's App::Ack. Assuming approval from modules@perl.org, my application will use the App::XXXXXX namespace. The cli goes in scripts and is just a wrapper around the main App::XXXXXX.pm.

Andy Lester seems to use his own server for the App::Ack website, Google Groups for the community mailing list (including developers), and Google Code for the Subversion repo for developers in addition to maintaining the release version of App::Ack on CPAN.

Since a check organizer can be used by nonprogrammers, I'd recommend setting up an external website and mailing list as a community hub, as opposed to relying on CPAN and RT.

Because the user community for my application will likely consist mainly of people who are unfamiliar with perl, this node discusses ways besides CPAN that a user will be able to get the application.

While my application doesn't have a web interface, if it did I'd include the cgi files somewhere in the CPAN distribution, along with instructions for setting them up.
