BF2 question

[UltimateXerox]

Ok, I'm not going to lie here. I'm peruvian (yeh I bet Im the first one you see speaking english lol) and to be honest, we don't get games here, altho there's a huge warez place downtown. There's 1 or 2 malls and they do sell games, but at like 70 bucks each and they JUST got Hl2... so obviously, they dont have BF2.
I bought the dvd warez (it cost me 3 bucks...) and I tested to game to see if I wanted it, and its so bloody great! I want to buy it, so I asked the mall ppl for it and they were goin to call me if they knew some other store had it, but I'm sure sooner or later they'll have it. Now my problem is the following:

If they do get the disc, it'll be in spanish... I absolutely hate games in other languages other than english, I don't want to listen to "Comandante, necesitamos artilleria aqui!"

So I was wondering if I could:

1) Install the game with my dvd warez copy
2) Use my original cd key from my spanish version
3) Use a dvd mini image or that thing to run the game in english and not spanish

and finally I want to know if there's any risk my cd key could go public or be banned from online gaming cause that'd really piss me off since the game would probably cost 70, if not more, dollars here and the only reason why I'm buyin it its cause its a good game and I want to play it online.

Thanks
