Thank you! I am a bit technically challenged, so, I wasnt quite sure what I should get/need. :o)

I recommend buying the Agent18-brand case. It's thick plastic, semi-frosted for a nice visual effect, and has a cutout area for the dock, headphones, and click wheel. Apple sells them at their online store (or possibly at a physical Apple Store--I don't have one around, so I can't check.)
I'm buying a Nano soon, and plan to get the Agent18 case, plus the Invisible Shield. For the amount of money these things cost, a few more bucks invested in long-term protection is not a big deal.
