Hello,
1) We use WooCommerce hook to display all the meta and we don’t have code to show SKU only. Read the post how to use WC hooks https://businessbloomer.com/woocommerce-visual-hook-guide-single-product-page/ 2) You can use translation files to change the strings that have “wishlist” http://xstore.helpscoutdocs.com/article/30-base-theme-translation but instead of real translation just change the wishlist to what you need. Let me know if it helps and provide the screenshot of the string you need to change.
Regards
