My Bing rewards just jumped up 22,000 or so points...

Did your lifetime total go up as well? If not, it's probably a glitch. Come to think of it, it's probably a glitch anyway. It's definitely a glitch.
 
To someone not living in the US, what can you do with Bing Rewards? I mean what kind of stuff can you get?

Mostly small gift cards. A few Microsoft related service bonuses... OneDrive space, ad free email etc. You can also use your points to enter sweepstakes to win Microsoft items... Surface pro, Xbox etc.
