iTouch 3g has similar look to 2nd gen (chrome look and oval wifi antenna, black volume button on side) except that in iTouch 3Gen at the back underneath capacity statement, there are 2 or 3 lines of description text (where as 2nd Gen has more than 3 lines of text).
No, You'd probably have to buy a new one

Most accessories that are compatible with the second generation are compatible with the third generation.
Yes 2nd and 3rd generation ipod touch have speakers build in
On amazon the prices go from about $195-$320 depending on which GB you want.
If it's a third verse a second generation it's very easy. The third generation has a camera on it the second gen. does not. If it's between the third and the fourth. It's more difficult so you should probably compare them on apple. It mainly has to do with speed, gigabytes, abbilitties, and some wi-fi connections.
The 3rd generation iPod Touch (like the 2nd generation) has built-in internal speakers that will play music out loud.
2G means Second Generation. So it is a Second Generation iTouch.
Yes, the iPod Touch 3rd generation, like all preceding generations, have a built in Wi-Fi receiver in it.
The most recent iTouch is the iTouch 3rd generation, which is the newest one available.
No there is not. As of now if you would like an iTouch that looks like a second generation iTouch you should get a second generation iTouch.
