To set the default products sort order to descending on products_id (= new products on top) change:

//// control string sort page
	if ($sort_by && !ereg('order by', $sort_by)) $sort_by = 'order by ' . $sort_by ;

To:

//// control string sort page
	if ($sort_by && !ereg('order by', $sort_by)){
  	 $sort_by = 'order by ' . $sort_by ;
	 }else{
  	  $sort_by = 'order by ' . 'products_id DESC' ;	 
	 }

(Sorting the columns would involve a lot more changes BTW)
