I am running Maestro 9.0 natively on Windows XP and locally. Im thinking of upgrading to a quad core processor. Does the software use all four cores?

Schrödinger's computationally-intensive products (e.g., Glide, Jaguar) are capable of using multiple processors. However, on Windows, due to the lack of OpenMPI support, this mode is limited to "distributed/batch" usage, i.e., processing multiple ligands simultaneously rather than "true parallel" mode.

The Maestro process itself is single-threaded, so there is no performance advantage to having Maestro itself on a multi-CPU machine. However if you are running jobs locally as well as running Maestro, a multi-CPU machine will result in a performance improvement.
