Few wordpress issues need fixed

Hello! Our website www. countrymusicislove .com has a few minor issues. 1. There currently is a hack in our [login to view URL] file that is adding a div on certain pages. I believe something with the entire css layout is wrong requiring this hack. Some areas are still not fixed. For example <[login to view URL]> the side bar is on the left side. This only happens on certain categories Is it possible to fix the css for good so that it always works? 2. Our tweet button works great. Only problem is that the full website post url is at the end of the tweet. This needs to be removed. A twitter plugin might need to be used to get this working correctly. Thanks
