But gravity is caused by the discrete particles (those with mass), so is it really continuous then? A discrete particle could only move in discrete steps, causing discrete jumps in gravity, would that be right?

And if gravity is continuous, could it store infinite information (for all the same reasons, having arbitrarily precise values) then?

Of course the field can be continuous, even if the weight is exactly some rational number. "Discrete steps" just means that the value differences in gravitational waves is also discrete. A bigger problem, where relativity clashes with QM, is stuff like singularity and superposition. We don't have an answer for that yet.
