Reply To: The display order in the item card. Change the text of button "add to cart".

Hello,

1) You can change this order by customizing some woocommerce action hooks. Try to add the following code to your child theme functions.php file

remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_excerpt', 20);
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_excerpt', 35);

2) You can change this word in WooCommerce POT file with Loco Translate plugin. Here is a video tutorial https://www.youtube.com/watch?v=tAFq1yTfWfU
and here is custom CSS to add icon to the button

.single-product-content .cart .button:before {
  content:"\f07a";
  font-family: 'FontAwesome';
  display:inline-block;
  margin-right:5px;
}

3) But you want to show select attributes before description according to first question.
