D3DTS_WORLD transform not working..

Are you calling
dev->SetTransform(D3DTS_WORLD, &pos);
Twice on purpose or is that a mistake?
well I don't think it matters, though I've tried calling it once inside the loop, once outside the loop and inside and outside the loop. If it doesn't work once it isn't going to work any other way but it's wortha shot regardless :P
Does your effect/technique use a vertex shader? The fixed-function transforms (Dev::SetTransform()) and lighting are disabled if a vertex shader is enabled.

oh ok, I see.
Yes it is, I'm still new to shaders so it was a pretty obvious mistake.
I just went through the DX sdk and it looks like I should use something along the lines of mFX->SetMatrix(), if I don't get this to work I'll come back though I have a strong hunch it's what I'm supposed to use.
Effect::SetMatrix is a good choice here. In your vertex shader function, you can use that matrix to transform the geometry.
Do note that you have to communicate your view and projection transforms to the shader too, in order to achieve similar results to the fixed pipeline.
