How to replace dash lights?

Some of the lights that illuminate the ventilation controls (fan, temp, etc.) on my 2005 Tacoma have puked. I'd like to replace them, and I don't want to damage the dash, since I have no experience with this sort of thing, and can't see where to begin. Any tips? I want to pull the panel in the lower part of the center of the dash, where the 3 round ventilation controls are, below the clock and the button for the 4-way flashers.

 

If no one else has a specific way to do this - there are a few threads I've run across for interior light mods here. I believe they had instructions and pics that included pulling these bezels. Try searching for dash light mods and it may pop up.
