No there is no app that allows you to record your ipod while playing games without jailbreaking it first.
For all I know, you must 'Jailbreak' it. I think there is a way to screen record using a capture card, but I am not sure!
If you have an iPod with click wheel i.e. iPod Classic, iPod Nano, 5G iPod and such all you have to do is start playing a song, then in the now playing screen press the center button until you see the lyrics. If you have the iPod touch however simply play a song and on the now playing screen touch the center screen and the lyrics show up.
Use an emulator for an iPod or any other Apple device. Then use Fraps or any other recording computer software to record your screen.
Get the Reflector App, which is available for a free temp trial and available for full purchase. It records whatever is on the screen and any sound playing from your iPod Touch/iPhone simultaneously. Basically 'Fraps' for iPhones/iPod Touches.
Depends on the iPod. The volume on any iPod with a click wheel can be changed by moving your finger in a circular motion on the wheel while playing a song. If you are using a touch screen iPod (or other Apple product), move the circle on the blue bar that appears on the screen while music is playing, or us the two buttons on the side of the iPod.
