Elite
elite has much more space for games and is the only way to go if u play on live
Yes, a 120gb can go into an elite, arcade or pro.
Microsoft says the difference between the standard (not elite) and arcade is: There is a difference in hard drive size Xbox 360 Arcade cannot play ALL original xbox games. Arcade comes with arcade games such as Uno Arcade is cheaper By pro i believe you mean "elite console". The elite console is black, not white and has a MASSIVE hard drive. But the elite is very expensive. I would go for the standard.
Yes, about 300+ X-Box games work for the 360. However, you can only play them on the Elite, or you can get a software emulator for the original 360/360 Arcade.

Some games, but not all of them.
Nearly all Xbox games should work on the Xbox 360, but quite a few don't.
no it can go on any xbox 360 console cause i have the arcade and it plays fine on that
Yes
It depends, the difference is the regular 360 has a smaller hard drive. I would recommend the elite because I bought a regular xbox 360 and with the map downloads and data downloads for games I later had to buy a larger hard drive. So in my opinion if I had to buy a new one I would go with the elite even if it is more expensive. http://www.xbox.com/en-US/hardware/compare101.htm
Because some of them aren't transferrable to it. For instance if you go to gamestop and buy a game if it has BC then it will work if not it won't.
No, Xbox 360 games can only be played on the Xbox 360. However some Xbox original games can be played on the Xbox 360.
