We report on the status of our understanding of the major expected polarization signatures of X-rays emitted by accreting neutron stars, and on how we can explore these signatures with the GEMS mission. In canonical accretion-powered pulsars, the most useful signatures appear in pulse-phase polarimetry (PPP). Different shapes of the X-ray emission beam display different characteristic signatures when the pulse-phase variation profiles of the polarization parameters (polarization amount and angle) are studied as functions of the X-ray energy. We discuss the importance of the cyclotron energy and the vacuum resonance energy in this context. We report on the progress in constructing simulation ``atlases'' of these PPP signatures, and on the inclusion of additional physics of radiation transfer in these simulations to make them sate-of-the-art. In canonical, bright, nonpulsing low-mass X-ray binaries (LMXB), the most useful signatures appear in the power-density spectra and cross-correlation spectra between polarization and intensity. We report on recent calculations of these signatures. We briefly discuss accreting millisecond pulsars and burst oscillations in LMXBs. We conclude by discussing our optimization strategy for observation of these X-ray sources with GEMS.
