Yeah that is good. Below 20hz you can't hear anyway. Above 20khz some people can hear and others can't depends on how good your hearin g is.

Yes and no.
Humans CAN sense frequencies below 20Hz. e.g. A tiger off in the distance roars, but you aren't in hearing range, yet the low frequencies travel far enough and your hair suddenly stands up on end. So, yes. You can "hear/sense" frequencies below 20Hz.
However, for normal playback, this isn't important. MP3s have crap frequency range and it won't make a difference.
The important thing isn't the iPod, but the format of the audio file and the earphones/headphones that you use.
Check on the AAC format for those frequency ranges. (I think they are about the same as MP3.)
Also, check the specs on your headphones. That is the most important. There are some kick-ass headphones out there that can give you 3Hz~40KHz. That is MASSIVE! They also cost 2.5x ~ 5x the price of an iPod...
