The Euro schools like IE, ESADE, IESE, Bocconi, etc. you have a reasonable shot - they're sweet spots and where you should focus your efforts, assuming you're looking to live/work in Europe post-MBA. Maybe add Oxford and Cambridge to that list. LBS will be a stretch school (you'll need a bit of luck, but you have enough of a shot that it's at least worth applying). Stanford and Wharton are long shots - if you apply just know that it's extremely unlikely you'll get in, even with the best possible applications.
As for the AWA, don't worry about it - adcoms don't really look at it. As for the NGO, you're making too big of a deal -- whether you can verify it or not isn't really that important because what adcoms are going to be focused on is your professional profile.
