1.) Broken condition doesn't seem to have provisions for magical items, so I would say they're affected.
2.) Depends on how the Oracle is using the gauntlets, and what he/she is using them for. As weapons? I'd have to say they get the penalty just like other weapons (gauntlets are still in contact with the tender parts of the body). In addition to weapons? Again, probably, as they would still be in contact with the injured skin. As a stand-alone magical item (Gauntlets of Ogre Power, for example), then there wouldn't be a penalty to apply there, as the gauntlets aren't doing anything other than granting a bonus.
