Question

Is there any need to use both wp_reset_postdata() and wp_reset_query() together?

Is it a case that I would pick one of the two functions; is there any point in doing this after a query :

 wp_reset_postdata();
 wp_reset_query();

There's no need to use them both.

You should only use wp_reset_query(), if you modified query with query_posts() (which you should avoid). This function also call wp_reset_postdata() - http://core.trac.wordpress.org/browser/tags/3.4.1/wp-includes/query.php#L95

So it's better to use wp_reset_postdata() after running separate query.
