Just some quick notes.
Firstly, don’t give your customers all those buttons! They will end up breaking something!
Secondly, although they bang on about a jQuery version, I just could not get it to work!
Probably the most important factor here is adding images etc. Without buying some $50 plugin, its actually one line of code!
Anyway, here’s a typical setup from one of my sites:

<script type="text/javascript" src="/js/tiny_mce/tiny_mce.js"></script>
<script type="text/javascript">

$(document).ready(function() {
plugins : '-example', // - tells TinyMCE to skip the loading of the plugin
    mode : "textareas",
    theme : "advanced",
    theme_advanced_blockformats : "p,div,h1,h2,h3,h4,h5,h6,blockquote,dt,dd,code,samp",
    theme_advanced_buttons1 : "image, bold,italic,underline,separator,strikethrough,justifyleft,justifycenter,justifyright,justifyfull,bullist,numlist,undo,redo,link,unlink,formatselect,code",
    theme_advanced_buttons2 : "",
    theme_advanced_buttons3 : "",
    theme_advanced_toolbar_location : "top",
    theme_advanced_toolbar_align : "left",
    theme_advanced_statusbar_location : "bottom",
 editor_encoding: "raw",
    remove_linebreaks : false,
    convert_newlines_to_brs : true

// Example content CSS (should be your site CSS)
content_css : "css/style.css",


//adding your images ionto the tinmce window
img = '<img src="http://your/url/to/image.jpg" />';
