We take two themes in algebraic geometry which are well understood and indeed classical in the case of curves - Brill-Noether theory of a general curve, and the theory of syzygies of a high degree curve in projective space - and we study analogous questions in the less well understood setting of higher dimensional varieties. Specifically, we focus on those higher dimensional varieties which are symmetric products of a curve: in the first case, we describe the geometry of parameter spaces of effective divisors (``divisor varieties") associated to these symmetric products, indicating how the properties (new in the higher dimensional setting) of singularity and reducibility of these divisor varieties reflect the geometry of the underlying curve. In the second case we study how much syzygetic information about an embedded curve - that is, information about the equations defining the curve in its projective embedding - can be transferred to its symmetric product when the latter is embedded in projective space in a natural way using secant planes of the embedded curve.
