Re: Wavefront .obj import /export vertex order
Any change in the structure of the object will affect the list of vertices but if you are simply loading/saving, the order should be preserved.
There is one UV coordinate for each vertex reference, so in a way, the vertices are not important. A cube made from quads has 8 vertices but 24 UV coors (4 on each square side. If the cube is made from triangles, then there would be 6 UV coors on each side.
To copy a UV from one object to another, the object structure (well, the surfaces) would need to be identical. I suppose it would be possible to implement but I think the application would be limited. You're probably best duplicating the object and adjusting the vertices as desired.
