For your first question, it's hard coded in album.php.

Find:

PHP Code:

    if (!in_array($sort, $valid_sort))
        $sort = 'posts';
}
else
{
    $sort = 'posts';
} 


Replace posts with username in both instances.

Then find:

PHP Code:

    if (!in_array($order, $valid_order))
        $order = 'desc';
}
else
{
    $order = 'desc';
} 


Replace desc with asc in both instances.

I'm not sure what you mean by redundant for your second question. Member Album is the parent feature, where as you can consider "signatures" and "profile pictures" to be its children. (clicking "Member Album" takes you to the default "profile pictures" view.
