Don't make too much fun of me... but the Shader Tutorial By Drew, which was based on the DX8.1 shaders that worked with version 6.22 of the engine is where i'm staying at the moment...
this seems to be working consistently, and i am able to get what looks like nicely lit bumpmapped objects... correctly lit by a light coded to follow the view (camera) around.
i can't seem to get anything to work right with the DX9 Shaders... especially trying to get something that looks near realistic dynamic lighting.
i'm gonna stick with this until the next step forward... and Drew puts out more tutorials
yeaaah... i know... i'm a whimp burger...
