The V3 to V2 figure has V2 style mapping, so will take V1/V2 textures. The head will take V3's head morphs, but the body has no morphs at all; and being a different mesh, won't accept V2 morphs directly. However I did have some success transferring some of V2's body morphs using The Tailor - a newer program such as Dimension3D's Morphing Clothes might do a better job.

Sorry, but you can't buy it. :-(

However, you can download it for free from here. :-)
