Bookmarks toolbar, hopefully quick fix. (Firefox 2.0)

I was hoping someone could help me modify my userchrome to remove the favicon, and instead add 8px padding to both sides of the text to have a similar look, but centered rather than right-aligned-looking.

At the moment I have hidden (not set display:none) the favicons, so it leaves a 16px padding, but all this padding is to the left, and I was hoping to instead go for 8px on both sides.

TUIA, everyone.

Here's a screenie of what it looks like now:

Here's a copy of my userchrome.css:

/*
 * Edit this file and copy it as userChrome.css into your
 * profile-directory/chrome/
 */

/*
 * This file can be used to customize the look of Mozilla's user interface
 * You should consider using !important on rules which you want to
 * override default settings.
 */

/*
 * Do not remove the @namespace line -- it's required for correct functioning
 */
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

/* Hide bookmark icons in the Personal Toolbar */
toolbarbutton.bookmark-item > .toolbarbutton-icon {
  visibility:hidden; width:5 !important}


/* Fonts 
menubar, menubutton, menulist, menu, menuitem, textbox,
toolbar, .tab-text, tree, tooltip, sidebarheader, statusbar
{  font-size: 8pt !important;
	font-family: Lucida Gr !important; } */

/* Hide icons for bookmark groups in Bookmarks menu */
menuitem.bookmark-group > .menu-iconic-left {
  display: none; }

#toolbar-menubar {
min-height: 12px !important;
padding: 0px !important;
margin: 0px !important;
border: none !important;
}
#nav-bar {
border: none !important;
padding: 0px !important;
}
#PersonalToolbar {
border: none !important;
}
#navigator-toolbox {
border-bottom-width: 0px !important;
}
/*
 * Some possible accessibility enhancements:
 */
/*
 * Make all the default font sizes 20 pt:
 *
 * * {
 *   font-size: 20pt !important
 * }
 */
/*
 * Make menu items in particular 15 pt instead of the default size:
 *
 * menupopup > * {
 *   font-size: 15pt !important
 * }
 */
/*
 * Give the Location (URL) Bar a fixed-width font
 *
 * #urlbar {
 *	font-family: monospace !important;
 * }
 */

/*
 * Eliminate the throbber and its annoying movement:
 *
 * #throbber-box {
 *   display: none !important;
 * }
 */
