nearing the home stretch

Hi,

I'm working on a module that I hope to place on CPAN in the near future. 
I have an account, and a name space, and I've written tests and pod for 
my module. My module name space is Gtk2::Ex::MindMapView, and I have 
several modules in this name space. For example,

Gtk2::Ex::MindMapView
Gtk2::Ex::MindMapView::Item
Gtke::Ex::MindMapView::Layout::Balanced

Question 1) In my Makefile.PL do I specify all the modules or just the 
main one  (Gtk2::Ex::MindMapView)? How do I specify all the modules? My 
Makefile.PL is as follows:

use strict;
use warnings;
use ExtUtils::MakeMaker;

WriteMakefile(
    NAME                => 'Gtk2::Ex::MindMapView',
    AUTHOR              => 'James Muir <[email protected]>',
    VERSION_FROM        => 'lib/Gtk2/Ex/MindMapView.pm',
    ABSTRACT_FROM       => 'lib/Gtk2/Ex/MindMapView.pm',
    PL_FILES            => {},
    PREREQ_PM => {
        'Test::More' => 0,
        'version'    => 0,
    },
    dist                => { COMPRESS => 'gzip -9f', SUFFIX => 'gz', },
    clean               => { FILES => 'Gtk2-Ex-MindMapView-*' },
);


Question 2) What is the best practice when it comes to creating build 
scripts? Should I use Makefile.PL or Build.PL or both?

Question 3) Are test scripts for all modules required? I have written 11 
test scripts to test 13 modules. Is this acceptable? All modules are 
exercised by the 11 test scripts.

Thanks for your help.
