Rockstar Pro – Featured image (sizes and woocommerce visibility)

Ok so I have two main issues. I have recently put together a site utilising this theme and wanted to be able to specify which images appeared at the top of the individual pages. After finding that I could do this by upgrading to rockstar pro I have now got the option to specify which image should serve as the header image for each page which is great but... It now gives two main issues which I need to try and address... 1. On a lot of the sub level pages - the featured image associated with the page is bigger than the area that was pre-defined in the old theme (1600x900) - is there a way for me to specify the height that featured images should display to on sub level pages to avoid me needing to redo all of the images and reinsert them into the site manually. 2. In checking the option to allow featured image headers throughout the site it now means that my woocommerce products are displaying irregularly... I now see the featured image at the top before the product listing which looks all wrong - im looking for a way of stopping the theme from displaying featured images at all on the individual products within the store. I took two approaches to this - the first was to install a plugin to hide the featured image on selected posts (which worked but also hid the main image in the gallery as well as the product photos so that was no good. I also note that rockstar also adds options to hide the featured image on specific posts and pages but that doesnt seem to be the case on products for woocommerce... Can anyone suggest anything on these two please - really keen to try and get these resolved. Thanks a lot Ben
