  As part of the Z-PAndAS Keck II DEIMOS survey of resolved stars in our
neighboring galaxy, Andromeda (M31), we have built up a unique data set of
measured velocities and chemistries for thousands of stars in the Andromeda
stellar halo, particularly probing its rich and complex substructure. In this
contribution, we will discuss the structural, dynamical and chemical properties
of Andromeda's dwarf spheroidal galaxies, and how there is no observational
evidence for a difference in the evolutionary histories of those found on and
off M31's vast plane of satellites. We will also discuss a possible extension
to the most significant merger event in M31 - the Giant Southern Stream - and
how we can use this feature to refine our understanding of M31's mass profile,
and its complex evolution.
