The answer to point 1) is
no. Just the
existance of a Module on CPAN doesn't give you the right
to distribute it in they way you suggest. Many modules on CPAN will
allow you to redistribute them (but be aware of modules
that are GPL only, if your program isn't GPLed, it could
be that you cannot include the module in your program the
way you propose), but that is not implied by the module
being present on CPAN. All that is implied is that you can
distribute the module
as it is found on CPAN, which
will often be a tarball suitable for the
perl Makefile.pl;
make; make test; make install; route.
As for point 2), I would really loathe authors that put
Modules in (a subdirectory of) the directory executables
are found. Modules are modules, and should go into a module
directory, so they can be shared with other programs that
do play the game as it should be played. If you think there
are admins out there who cannot install modules, the proper
way is to write a document explaining how to install modules
instead of making a mess of some systems. Besides, you like
your programs to be used, don't you? Make a mess and garanteed,
admins all over the world toss your code from their systems
as fast as they installed it, and ban anymore code from the
same author.
