Layout is a bit more involved than just an admin setting...
In a COPY of includes/templates/template_default/templates/tpl_product_info_display.php FTP it to your local and peek at the contents using a PLAIN TEXT editor - - after editing, place in this location
includes/templates/mostlygrey/templates/ - - and if the folder does not exist, create it
Look and see that most elements are contained within bof & eof tags such as:
<!--bof Product Price block -->
All stuff between
<!--eof Product Price block -->
These are arranged in the order they are to appear and then styled using CSS.
One can move complete blocks relatively easily with cut and paste
So the first step is to rearrange the order to what you want and once the order is correct and if it is not displaying correctly using the stylesheet one can tweak/refine the display.
