Hello,

1,3. Try to use the below code for help. Paste the code to Theme Settings -> Custom CSS.

.product-grid-item:hover .wd-product-stock,
.product-grid-item:hover .star-rating,
.product-grid-item:hover .hover-content-wrap {
    display: none;
}

2. Sorry to say but right now there is no option in Theme Settings available for that. It requires Customization and this is beyond our limitations and support policy scope. Hope you can understand our limitations.

In this case, I suggest you change the product style via Theme Settings -> Product Archive -> Product styles.
