If a planet didn't rotate, would its gravitational force be stronger?

For instance, if the earth rotated less 900 mph, would the force we feel be greater?

The gravitational force would be the same, it depends only on mass, but the net force on objects that lie on the surface would be higher due to no inertia wanting things flying off the planet ('centrifugal force', but it isn't really a force itself, just a result of inertia).  

Objects not on the surface (i.e. orbiting the body) would experience the same net force if the body was spinning or not because the mass of the body is the same.  This assumes the body has homogeneous density.
