Superfish Menu Help

Hey guys,

I've created a superfish menu with a nav-bar style. The only problem is that it is not stretching to my site's width of 800px. Here is a link to the site: http://130.86.248.161/joomla/
I believe it may work for some browsers, but i know it doesn't for firefox and safari. Some browsers has the slideshow that is set to the module position under the navigation as being aligned with the navigation. So im hoping if i figure out the width problem it will also fix the slideshow position problem.
In superfish.css the parameter for width is:
.sf-menu ul li
{
    width:            100%;
}

but I'm guessing there is another spot I'm not looking at that is causing it to not stretch to 800px. Would it be in the Superfish.css, superfish-navbar.css, or my template.css that is causing this problem? If you need me to post my entire template.css let me know.
