This:

    if ($#ARGV < 0) {
        $file = StandardGetFile('', 'TEXT');
        if ($file->sfGood()) {
            push(@ARGV, $file->sfFile());
        } else {
          exit(1);
    }

puts up a dialog that allows you to pick a single file.  However, "$file" 
is loaded with the complete PATH to the file, so if you want the folder, 
rather than a file within it, you should be able to truncate the path to 
the last delimiter ":".  Note that the above assumes that you save the 
Perl script as a droplet and the STANDARD method of use is to drag and 
drop the required folder on it.

>2.) For the above, as well as the dialog in which they select their "MAME

You could use Mac::Dialogs to create a custom dialog, or GUSI allows you 
to "Choose" directories and files (also an alternative to the above). 
Most of this *IS* in MPPE.

>3. After the work is done, is there an easy way to set the file's

Since you're already using Mac::Files:

sub change_creator {
    my $has = FSpGetFInfo($file);
    $has->fdCreator("ttxt");
    $has->fdType("TEXT");
    FSpSetFInfo($file, $has);
}
