UV Unwrapping in Blender 2.59

[Your Computer]

In Blender, the part where the axises cross paths is basically the same position where the axises in the perspective view of the model editor cross paths. You'd want the bottom edge of the mesh to be centered there. After aligning it there, apply location again.

For the texture issue, do you have a .mat file that points to the texture that the mesh is mapped to (in the same directed as the .dae file)?
