Well, it's getting better. Change the background spec to "center" instead of "left" at the end of the line. There's still a problem with black in between the buttons.

This might do it:

.top_navbar_button
{
	font: bold 11px arial, verdana, geneva, lucida, 'lucida grande', helvetica, sans-serif;
	color: #ECECEC;
	background: url(images/styles/rirrakusu/style/navbar_button_bg.gif) no-repeat top center;
	width: 79px;
	text-align: center;
	padding: 3px 0px 3px 0px;
	margin-right: 1px;
}
.top_navbar_button a:link, .top_navbar_button a:visited
{
        background-color:#0808080;
	color: #ECECEC;
	text-decoration: none;
}
.top_navbar_button a:hover, .top_navbar_button a:active
{
        background-color:#080808;
	color: #669966;
	text-decoration: none;
}
