A few Magento Tweeks

We have a website [login to view URL] and have a few magento things that need to be fixed. They are.... - In our product info page we need our main image to be alittle larger. - We have a ratepoint review button at the bottom right of our website that needs to be uninstalled as their image isnt secure and is causing our cart to show a warning. - We had someone change the price on our catagory listing and product info page to $10 instead of $10.00. (removing the cents digits) however they made it where in the shopping cart and upon checkout its showing only $10 instead of the full $10.00 so its throwing off our shipping + tax end totals. (example customs end total is $14 however the acctual price is $14.35) WE NEED OUR CART TO SHOW CENTS DIGITS - At the top of the website we have 3 buttons (Facebook, Email/contactus, Live chat) We would like a facebook "Like" button install next to the facebook link button.
