moving the search button

[touchclothing]

if you look at the site http://www.digitalmarauders.com/theshop/ you can see that my search box and button are in the middle I wanted to find out how I can move this all the way to the right? And also change the search button from what it is to just a small glass icon?

Thanks

In your Stylesheet change this code

 
#navMainSearch {
float: center;
}

to this

 
#navMainSearch {
float: right;
}
