I don't know with which 3D app you work of course, but friendsofed have a book that's called Photoshop and 3D. Gary Bouton, the author of Inside PS has his own forum, the inside track on this board. He is also into 3D, so you may want to visit that forum (the bottom one).
Apart from that, feel free to ask any questions you like. If we can , we will come up with several answers so you may mix your own cocktail.
Welcome!
