I'm not really understanding what you want to do but I'll take a stab at it.
You've got a list of vertex positions in your target mesh
(target_mesh_verts)
You've got a list of component indices from your first mesh (indices)
I'm not clear on how you want to use them together.
You will probably want to do something like
for i in indices:
target_mesh_verts[i] = something
target_mesh.setPoints(target_mesh_verts)
Note that can fail (IndexError) if there are more verts in your first mesh
than there are in your target mesh.
