What connections are standard for image and bump maps in the material room?  I just started paying attention and noticed that some MAT poses don't make the connections.  So, I'm trying to figure out how to do them manually.

Image Maps:

Diffuse_Color
Specular_Color (or is this just for shiny parts like nails and inner mouth?)

Bump Maps:

Bump

Trans Maps:

Transparency
Transparency_Edge

Is this right, and is that everything?
