Well... you really can't if you wan't to do it by yourself. Since your screen is broken, call or email Apple about what happened and they will either fix your screen or get you a new one. They would do this because it's included in your warranty.
No, you cannot. iPod touch apps will only work with an iPod Touch or iPhone - no other touch screen mp3 player.
nah because it ain't no touch screen
Ipod Touch
Some do,not all of them
The iPod Touch has a heat sensitive screen. If you touch one with cold fingers it will not work.
it's turned off
You must use your finger (or other parts of your body made of skin) for all actions performed on the touch screen of your iPod Touch. It has been designed to only recognize skin and not touches from objects in your pocket or other annoyances. As a consequence, styluses and fingernails do not work on your iPod Touch's screen.
Upgrade to iOS 4. It's free. It won't work if you have an old iPod Touch (before September 2009) or any 8GB iPod Touch. You'll need to jailbreak to get wallpaper.
Call the company and ask for assistance. If it is within warranty, you can return it for another one.
It's probably broken

Because it's broken. Without more details, we can't be more specific.
