Changing the look of a 'Shop' page

Hi I have just setup a woo commerce shop page and want to change the look of the page. I have three questions: 1. I currently have an advertisement widget in the 'under content' area. I tried to set the visibility so the advert doesn't show on the shop page but it's still there. Can you help with this please? 2. I want to remove the featured posts at the bottom but there is no option to remove it. The only option is to set it on the homepage, put it on all pages or remove it all together. 3. I would also like to remove the sorting drop down option on the right hand side Is there CSS code or another way of doing these things? My website is www.musicfootballfatherhood.com Thanks Elliott
