You could have saved yourself a little time here.
Its been tried, tested, tried, tested and tried again.
The stock FPSC X9 shaders just dont stand up when creating normal and specular mapped segments.
Heres the info I provided which I've followed the TGC normal mapping segments tutorial for with screenshots.

I'm not sure why your segments are coming out greyscale. I've managed to get them working in colour but always fell over when trying to use the effect on walls and floors.
The bump mapping in FPSC X10 is much better and actually works properly which is probably why TGC haven't updated the X9 ones.
The relief shader included in the latest EFX Mod looks more promising though.
