Hatsune Miku does not come with anything but a lite version of VOCALOID4. ou should only need Miku though, as she comes with Piapro stuio which can act as a stand in for Vocaloid4.

Though for full capabilities, you need VOCALOID4.

This is it, all Vocaloids are the same (well, maybe not as V1s or V2s always came with the full engine which is why they were expensive), the other stuff is demos and bonus they include as trials. Some other studios do this too like Internt co., Ltd or Ah software.
