For one of my applications, I have all forms return an action (add, edit, delete, etc) and a type (Press Release, Press Cuttings, etc.). Then, I control the page and the function as follows:

#                    $action     $type
my %page_control = ( add    => { PressRelease => { page     => 'pm-mai
+n-pr-add.tmpl',
                                                   function => \&add_p
+ress_release },
                                 PressCutting => { page     => 'pm-mai
+n-pc-add.tmpl',
                                                   function => \&add_p
+ress_cutting }
                               },
                     edit   => { PressRelease => { page     => 'pm-mai
+n-pr-edit-del.tmpl',
                                                   function => \&edit_
+press_release },
                                 PressCutting => { page     => 'pm-mai
+n-pc-view.tmpl',
                                                   function => \&view_
+press_cuttings }
                               },
                     delete => { PressRelease => { page     => 'pm-mai
+n-pr-edit-del.tmpl',
                                                   function => \&delet
+e_press_release },
                                 PressCutting => { page     => '',
                                                   function => '' }
                               },
                     display=> { tabs         => { page     => 'pm-tab
+s.tmpl',
                                                   function => '' },
                                 menu         => { page     => 'pm-men
+u.tmpl',
                                                   function => '' }
                               },
                     default =>{ page     => 'pm-main.tmpl',
                                 function => \&show_main_console } );

my $page     = $page_control{ $action }{ $type }{ page };
my $function = $page_control{ $action }{ $type }{ function };

$page ||= $page_control{ default }{ page };

With that one data structure, it's relatively easy to track what's going on. However, I do want to look a bit more closely at CGI::Application as I lately hear its name getting bandied about quite a bit.
