I was once told to use an XACTO knife if that helps
No the air bubbles are just where a piece of dust or sand didn't get cleaned off before you put on the screen cover...completely harmless.
No. If you want a screen protector or case you have to buy one. The ipod comes with headphones and an instruction manual. If you're looking for a case or screen protector I suggest looking at Five Blelow.
They should do
I had my iPod Touch screen protector on for about a year and 2 months with heavy usage (brought to school and on bus). The protector even got some scratches on it. If it wasn't for the protector, my iPod would've been scratched up. It would be recommended to put a protector on the back of your iPod as well...
its the thickness the higher the number the thicker the creen protector
No
Get a case and a screen protector
No, the glass on an iPod Touch isn't just a protector. The glass is the touch screen, and without it, you don't have anything to touch, rendering the iPod Touch useless.
No there is not, you have to buy one separately.

It's up to you to choose, it's better to get a screen protector since scratches would mess up the touch screen and make it harder to use, but you dont have to get 1, just better to do.
If you're question refers to a screen protector on your iPod, and there's a bubble between it and the screen, try using a hair dryer to heat the screen protector around the bubble, and try pushing the bubble to the nearest edge, using your thumb. If it's not too bad, that should get it out. Don't use anything like a key (I wouldn't even use plastic), you can scratch the screen protector and leave bad marks on it.
