Sounds like fun! I hope you are able to learn what you need.
Never heard of Lynda.com, but I've heard good things about http://psd.tutsplus.com/
. Loads of Photoshop tutorials for free.
Here's another one that might be worth a look: http://photoshoptutorials.ws/
I know we have some graphics/audio/video experts who check in periodically, so hopefully they can chime in.
