There are multiple types of iPods with those generations.
There is the iPod Classic, the iPod Touch, the iPod Nano, and the iPod Shuffle. All of those types of iPods have a third and fourth generation, but you can compare the one you choose on Apple.com.
Very little noticable differences for the ordinary lay man. Although there is an improved HD screen.
The main differences are the sofware, making the thing harder to jail break or hack.
ipod touch 4 has camera and ipod touch 3 has no camera
The Ipod Touch 4 can come in different colors. The Ipod touch 4 has a much higher resolution than the Ipod Touch 3 as well, and the 4th generation has two cameras as opposed to one.
The iPod touch 4 is a major improvement on the earlier models. Some of the new features include a higher resolution screen, longer battery life and the addition of two cameras. However the screen can smudge with fingerprints easier than the iPod 3.
yes the 3rd gen is shorter but wider, fater and heavier
Yes

No. They are different. The iPod touch 4 screen has more pixels so the iPod touch 3 won't support it.
No only on sims three ambitions for the ipod touch
There is no way to get unlimited money in The Sims 3 Ambitions for the iPod Touch.
Unfortunately, you can't purchase or enter a cheat to have a gun on The Sims 3 iPod touch.
Ipod touch first generation is pretty slow, the higher generations have faster speed and are thinner than the first gen. The later generations of the ipod have more features. Ipod 4 has a camera also able to record video.
Yep.
No.
Apple has already made a 3rd gen ipod touch.
