A couple of questions about permalinks and borders

I just got my website up and running and there are a couple of issues, I’m having with it. This is the site countyfeedsupply.com. If you click on a page other than the home page, the address that shows up in the address bar is the url number rather than the name. I have the post name box checked in the permalink settings, but it shows the url number as well. How can I change this to show the web address and the page that is open?
My second question is on the pages such as the product page the photo at the top was inserted as a png file but it shows up with a light border around it. How can I remove it? I’m not terribly savvy when it comes to html and css so a non technical explanation would be very much appreciated. Thanks for any help
