According to the relevant page on Sigma UK website only the Nikon fit has the HSM motor. When ordering make sure you specify that you want Nikon fit.

As an all in one solution it should be OK. At the 200mm end the small maximum aperture is likely to mean the viewfinder is a touch dim and the AF may be a bit slow. As Nick (Benchista) says I have heard opinions that suggest the Sigma is actually a little better optically.

Personally I might be more inclined to get the D60 with the 18-55 VR lens (VR is Nikon's OS) and add the 70-300mm AF-S VR Nikkor which would ultimately give you longer reach, a better maximum aperture and I suspect an even more effective VR function.
