to show the price, edit the webassist/themes/Dark/css/dark_styles.css file.
change:
.productResultsWrapper .price {
font-weight:bold;
float:right;
font-size:16px;
margin-top:-204px;
color:#EF8D01;
}
to:
.productResultsWrapper .price {
font-weight:bold;
float:right;
font-size:16px;
margin-top:-24px;
color:#EF8D01;
}
to change the order that the products are displayed in will be trickier, you would need to edit the recordset on the webassist/plugins/catalog/results.php page to change the order by clause, this is not a supported modification.
