Ok, l'ho fatto funzionare. Non sono sicuro che sia la soluzione più elegante. Se qualcuno vuole intervenire con miglioramenti, sono tutto orecchie. Speriamo che questo possa aiutare qualcuno che ha un problema simile in futuro.
La mia domanda finale sul ciclo di articoli/prodotti:
// Get all Items associated with this category page
// ID of current category

$query->from( $db->quoteName( '#__k2_items' ) );
$query->where( $db->quoteName( 'catid' )." = " .$current_cat . ' AND published = 1' );
$db->setQuery( $query );
$row = $db->loadObjectList();
// Store Titles, Descriptions and IDs in arrays
foreach ($row as $value)
{
$product_ids_array[] = $value->id;
};
// Now we're going to get the IDs of the tags associated with the items
// Create comma seperated list of product ids
