Finding Surfaces on Newer Models
I'm having a hard time finding the actual objects under the "Surfaces" tab in the newer models.
When using older models (from pre-Iray days), if I wanted to change the texture on a specific surface, make the surface transparent, etc., I could select the model, go to the Surfaces tab, find the surface I wanted, and change the parameters.
I've noticed that some of the newer models, however, don't have the surfaces broken down in any way that allows me to select a specific surface within the model.
Is there any resource that has a breakdown of how the newer models (that I'm assuming are optimized for Iray) work under the Surfaces tab?

Try clicking with the Surface Selection tool to see what goes where. Also, bear in mind that over the gernations more parts have been split off to separate figures fitted to the base figure rather than being part of the base figure themselves.
