Yes. Hubble discovered it by examining the spectrum of light from a star that Europa eclipsed. Right before Europa covered the star, the star's light passed through Europa's atmosphere. The light was altered such that it showed oxygen in the spectrum.

Yes, in that there is a lot of frozen water that will sublimate rather than melt at times. Europa can't hold on to the hydrogen, but the oxygen will stay, as you say, tenuously.
