It would probably help to generalize the checking with a subroutine. This might help get you started. It would take the configuration setting and a hashref with all the relevant info. It would return the option and the message.

sub optionize { 
    my ($config_setting, $opthash) = @_;
    my $option_name = $opthash->{option}; 

   if (defined $config_setting && ($config_setting =~ /1|true|yes/i)) 
+{
       return( "--$option_name", $opthash->{msg_yes} );
   } elsif (defined $config_setting && ($config_setting =~ /0|false|no
+/i)) {
       return( "--not-$option_name", $opthash->{msg_no} );
   } else {
       return( undef, $opthash->{msg_default} );
   }
}

If you are going to keep a hash of all of the argument stuff, I suggest you make it an HoH where the subhashes are keyed by some canonical name for the argument. Lots of "F-arg" and "t_arg" and "t_msg" and "f_msg" keys are going to get nasty.

I also suggest that you think about using READMORE tags in long questions like that.
