Gnome panel missing application icons, chat bubble menu, and power menu

I've been messing around with my system too much and messed something up. I'm new to Ubuntu, but have been using linux on servers for a few years. I'm not sure of the correct terminology so I'm including screen shots to explain what is going on. First, system specs: > Ubuntu 10.4 LTS x64 Lucid Core i7-970 Nvidia GTX 480 Dual Screen with Twinview Nvidia proprietary dev driver 260.24 (64-bit) Now what I screwed up: First major customization was ppa:goehle/goehle-ppa customizations for keeping evolution open after closing the main window. That worked fine until I started messing with getting hibernate working. I never got hibernate working even after installing linux-generic-tuxonice; it gave a warning about usb09 not stopping. The only things that I have in USB are a keyboard and mouse. Then I started getting the error: Trying to fix this, I reinstalled the Evolution customizations. The error persists and now the panel is messed up as well. I'm not getting the application icons, the menu with the chat status, or the shutdown/restart/lock screen menu. This is what it should look like: But this is what I'm getting now: How do I get my icons back? --- **EDIT:** I found how to get my application icons back. 1. Right-click on panel 2. Add to Panel ... 3. Notification Area. I still have not figured out what the chat bubble menu and power menu are called.
