Creating a metabox to upload multiple images, Ignoring The Featured Image

1. Generally speaking, I would take the approach of querying for post attachments, but withhold the attachment that is the post thumbnail. WP provides a simple way of finding the post thumbnail ID with get_post_thumbnail_id (Codex Ref). To modify the code from the other post, I would add the following parameter to the $args array to withhold the thumbnail attachment from being queried:

   'post__not_in' => array(
       get_post_thumbnail_id($post->ID)
   )
   

   The post__not_in parameter will “Specify post NOT to retrieve.” (Codex Ref)

   To put the whole thing together, the code would look like:

   $args = array(
       'post_type' => 'attachment',
       'numberposts' => null,
       'post_status' => null,
       'post_parent' => $post->ID,
       'post__not_in' => array(
           get_post_thumbnail_id($post->ID)
       )
   );
   $attachments = get_posts($args);
   if ($attachments) {
       foreach ($attachments as $attachment) {
           echo apply_filters('the_title', $attachment->post_title);
           the_attachment_link($attachment->ID, false);
       }
   }
   

   In order to further fine tune your queries, I would highly recommend exploring the WP_Query class (Codex Ref). It’s power is only rivaled by its ease of use.

2. You could basically use the code from that other question and then filter out the featured image by looking at the post thumbnail ID.

   foreach ($attachments as $attachment)
   {
       // Skip the post thumbnail
       if ($attachment->id == get_post_thumbnail_id())
           continue;
   }
   

   Codex: get_post_thumbnail_id()
