Specifying that toString returns a non-null result is good.  Specifying that the methods don't throw any exceptions, or an implSpec that the methods shouldn't throw is okay.

I'm less sure about the proposed wording for resource usage. For hashCode then maybe it should say that the hashCode method may be called very frequently and should be as fast and use as few resources as possible.
