As I understand it, the idea under quantum gravity is that attraction between objects is meant to be as a result of the exchange of virtual gravitons.  I'm not sure though how this reconciles with the relativistic view of gravitation - if the attraction is due to particle exchange I would think that means that there is nothing relating to the curvature of space-time; but then there would be no mechanism to explain phenomena such as gravitational time dilation.

Could someone please try fill in the gaps in my logic?

The existence of a graviton does not exclude the curvature of space-time as the explanation for gravity. Think of it like this: the graviton "communicates"  the curvature of space-time to any massive bodies affected by that curvature.
