Well, I don't know which ones you're talking about specifically, so I'll just name off some stuff I've done to both of my taskbars.
Um, the Pokeball start button was custom made and inserted by myself.
The bars under that are provided by Windows Live Plus, called Contacts on Desktop, I suppose. And the bottom bar is a combination of ObjectDock, and Rainmeter. You can probably just Google them and get these as the top listings.
(ObjectDock is what powers the icons you see on the left on the bottom taskbar, and Rainmeter actually makes the task bar and powers the system information on the right)
