What do you feel is missing? 

 

To begin with - I've just followed your link to Render settings it gave me no information at all on the settings available in Iray - I would like to know what all the individual settings do, what they are for etc.

What difference does increasing the Rendering Quality make and in what sort of increments should it be increased.

That's just an example.
