Hello,
1) We’ll change it in next theme update.
2) You have asked about https://fonts.googleapis.com/css?family=Raleway%3A700%7COpen+Sans%3A400%7CRaleway%3A500 don’t understand your answer about fontawesome.
3) Unfortunately, WC has only 3 variants of the images – catalog, single product, thumbnails. And we use them for appropriate images in our theme. So, you may go to WooCommerce > Settings > Products > Display > change catalog images to 300×300 and regenerate thumbnails. Check if it helps.
Regards
