shaders

You can find some very good articles on the developer section of nvidia.com, also there is an article called Introduction to the DirectX9 High Level Shading Language which I found very useful, that is of course if you want to use the HLSL.

Also this site:

www.facewound.com/tutorials/shader1/

Has a very basic tutorial which will ease you into things a little more.

When you have an idea of what is going I am sure you will find that the good people here on Gamedev.net will help you with any more specific questions you might have.

Oh I almost forgot, check out the DirectX SDK, for some information. IMHO this is crap overall but there are a few things in there that may be useful.

At nVidia's developer site you will find LOTs of .FX files. You can then load them up in nVidia's FX Composer.
