Texturing/texture Shapes For Models

Hi,
I wanted to ask if someone can tell me, how to get/do the shapes of the different model parts I need to texture the model later via Photoshop. And how do I define them and that stuff?
Thanks.

I understand your question to be this: how can i put a specific image from Photoshop on a specific part of my model?

If you are using polygons, the answer is UV Texturing, and you can look up that term in Maya help to get started:

Search for "UV texturing" and then select the Tutorial: Getting Started with Maya: Lesson: UV texture mapping: Mapping UV texture coordinates
