Sure
Add this to your custom css:
@media only screen and (min-width: 768px) {
/* IMAGE AREA */
.woocommerce div.product div.images {
width: 30%;
}
/* DETAILS AREA */
.woocommerce div.product div.summary {
width: 67%;
}
}
For the tabs, you just need to add the info, such as the product description, addition info which is the attributes etc
