Answer 1

Made two changes

1. Added a top padding of 25px to li for the image

   #TopMenu ul li {
   display: inline;
   list-style-image: none;
   list-style-position: outside;
   list-style-type: none;
   margin: 0px;
   padding: 25px 4px 0 6px;
   }
   

2. changed the logos background-position:center; ( Please note that I have used short hand notation )

   #TopMenu ul li.home {
   background:url('http://cdn1.iconfinder.com/data/icons/munich/16x16/home.png') no-repeat center;
   height:16px; width:16px;
   }
   #TopMenu ul li.home:hover {
   background:url('http://cdn1.iconfinder.com/data/icons/cologne/16x16/home.png') no-repeat center;
   }

P.S: Please note that I am using #TopMenu and markdown is not working properly.
