The place you need to change the CSS is in vbulletin.css

Search for:

.navlinks {

Replace CSS with:

.navlinks {
    background: {vb:stylevar navlinks_background};
    border: {vb:stylevar navlinks_border_top};
    padding: {vb:stylevar padding} 0;
    text-align: center;
    color: {vb:stylevar navlinks_color};
    font-size: {vb:stylevar font-size};
    margin-top: 20px;
    margin-bottom: 20px;
    width:100%;
    clear:both;
    -moz-box-shadow: -2px 2px 2px {vb:stylevar shadow_color};
    -webkit-box-shadow: -2px 2px 2px {vb:stylevar shadow_color};
}

Then use stylevar navlinks_border_top to control the border around the nav links.

Use stylevar shadow_color to set the shadow color around the navlinks.
