Giving up on strict halfway, isn't good practice, and so is dereferencing your data using @$ and %$.
This been said, stuff like ARRAY(0x1d9d144) and HASH(0x8862690) refers to un-dereferenced reference. In this view:

if ($k eq "inputs"){
        print "\n\nINPUTS\n";
        foreach my $thisItem(@{$v}){
                my %tempHash = %{$thisItem};
                        foreach (keys %tempHash) {
                               print "$_ $tempHash{$_}\n";
                        }
        }
}

Read the perlref section of perldoc for more information. And, as suggested above, the actual documentation of what the modules you use actually return, and handle it accordingly.
