Thanks for the help. Number 2 worked perfectly, however, number 1 is still unresolved. It appears that changing the size within the WooCommerce settings and re-generating thumbnails does not change the product image size within the individual product page.
Currently your single product image size is 100px X 100px. Can you please make sure you’ve change the image dimension from WooCommerce -> Settings -> Products -> Display -> Product Images -> Single Product Image
