Could I get a precise tutorial for editing a mesh file in Blender?

Sure enough, it was the simple fact that I hadn't ticked a damn box. Selecting Fallout 3 on export made the nifs readable in GECK. Good lord what a silly oversight. Thank you all for your time.

Yeah a lot of times it's something simple. With so many options it's easy to overlook something.

 

Glad you got it sorted out.
