Add custom shortcode button to Editor

Before the new version of WordPress 3.0 came out I was using this jQuery code below to add custom buttons for my own shortcodes to the editor toolbar in the admin panel, it worked great. However with version 3 out now, it has stopped working, if I view source in admin panel I can see my code below is being loaded properly, it just doesn’t work anymore, does anyone know what has changed or how to fix to work with the newer version?

WordPress Featured Post Slider

Alright, I have almost finished up a clients project in WordPress, but I have hit a wall. I am not really great with jQuery (and I have yet to find a plugin to achieve what they are looking for). The client wants an automatic slider on the homepage that pulls in featured posts out of their five categories. I have scoured the net for plugins to achieve the “look” they want, but to no avail.

WordPress Enqueue Script Chaos (jQuery & Foundation.js)

I’ve been working on building a theme for the past couple days now, and I’ve run into a wall. While I originally included foundation.js as an enqueued script, I couldn’t remember why I had added it. Today, when I tried removing it (to improve page-load speed) from my functions.php file, it messed up all of my jQuery plugins.
