No sites, unfortunately, at least that I'm aware of.

If you're targeting DX8, then the transition should be fairly smooth 
(depending on how much OGL you were using).  Most of the state stuff has 
direct analogs.  Probably the biggest area of confusion for me was making 
sure my matrices were matching correctly.  I don't remember the exact 
details, but it took some trial and error before I figured out how to map 
an OpenGL projection matrix to the D3D one.
