Yes light bends around gravity. You can see it during a lunar eclipse, light will bend around the moon and distant stars will be shifted over a bit compared to when there is no moon in the way.
And yeah, you are encountering contradictions. Not sure if those have actually been answered by scientists or if they just chalk it up to one of those things.
I'm not so sure they actually know what makes up light. I think the photon has a shady past, but i'm sure these other guys in here know a lot more.
