Answer 1

If I'm understanding correctly, you're making it too hard. All you need to is use wp_get_attachment_image_src

$test = get_post_meta($post->ID, 'full_image', true);
$image = wp_get_attachment_image_url( $test[0] );

Answer 2

To grab the guid from your array, you will have to call it like that:

<?php    
    $image = get_attached_media('image', $post->ID);
    $image_guid = $image['guid'];
    echo $image_guid; //will echo the guid URL
?>

Answer 3

Got it working using this method:

$this->set_full_image(wp_get_attachment_image_url( get_post_meta($post->ID, 'full_image', true), 'large'));

The reason that I wasn't getting any results back is because get_post_meta was returning an array and not a single value so I had to set true at the end.
