In /includes/templates/your_template/templates/tpl_product_info_display.php, find the block of code beginning with <!--bof Product Price block --> and ending with <!--eof Product Price block -->. Move it to just below the <!--eof Add to Cart Box -->, and then you can fine-tune the position in your stylesheet. This will put it under the box. To put it in the box, *carefully* insert the code into the bottom of the add to cart div.
PHP Code:
<div id="cartAdd">
<?php
echo $display_qty;
echo $display_button;
?>
</div>
<?php } // display qty and button ?>
<?php } // CUSTOMERS_APPROVAL == 3 ?>
<!--eof Add to Cart Box-->
Insert between the ?> line and the </div> line.
For the "larger image" link, add
.imgLink { display: none;}
to your stylesheet.
