The short answer to the question of how to set up two different cameras, one with a perspective projection and one with an orthographic projection, is: set up two different cameras, one with a perspective projection and one with an orthographic projection.

I'm guessing that's not really what you're asking though :) Is it 'layers' that you're looking for, perhaps? That would typically be how you'd associate certain objects with one camera and other objects with another. Other things you might be interested in are the camera 'depth' field (through which you can specify that the UI renders over the game world), and 'clear' flags (which you can use to make sure the UI camera doesn't erase what's already onscreen when rendering).

Were you asking for links related to clear flags and layers? If so, just check the documentation; all the info you need should be there, I think.
