Don't worry too much about this prize - I've seen the last two Gala performances (Berlin in 1999 and Stuttgart in 2000) and the audience never completely understood who won and what for. Each Gala had the critics complaining about strange nominations and even less credible winners. It's always interesting to compare the members of the jury and the nominees - usually each jury member brings one or two of his dancers along. I'd like to know how they finally choose the winners...
At first this was intended to be a prize like the Oscar, but for dancers: best female dancer, best male dancer, best choreographer. Later they also nominated designers and composers, only to skip that category in the following years.
Maybe you are interested in the winners until now:

No Prix Benois in 2001, as far as I know.
Interesting that both Altynai Asylmuratova and Nina Ananiashvili never received the Benois de la Danse - was that by Jurij Grigorovich's influence? This prize is still pretty much under the control of the former Bolshoi director.
