Wordpress - Multiple featured image thumbnails for post types (Multiple Post Thumbnails plugin)

Dude, you're doing this the hard way. You can do what you want totally with a single 'featured post thumbnail'. Read the documentation about thumbnail sizes in themes. You can inject custom thumbnail sizes in your themes funcitons.php and then give them as a parameter to the (get_)the_post_thumbnail() function. Please just read the documentation at the Codex - start with the function reference page for the_post_thumbnail(), maybe - and you'll see. Wordpress does automatically resize and crop the image for you, if only you tell it to do so.
