Does spacetime curvature of EM field affect zero-charge particles?

[splur]

I've read in a few places that the energy and momentum of the electromagnetic field will itself induce a curvature of spacetime, much like the presence of matter. I'm not very familiar with general relativity, but does this imply that particles with mass and zero charge will still be affected by an EM field?

Yes.
