Phase space can be any generalized coordinate and conjugate generalized momentum pairs. Note that these are not necessarily physical coordinates.
Spacetime is exactly what it sounds like, 3D physical space with a 4th temporal coordinate. The time coordinate will have an inverse sign in the line element.
