I am completely new to Carrara, having had brief exposure to C5pro in order to get the 'free' C6pro upgrade. My understanding from the 'marketing hype' for C6pro was that it doesn't include a separate plug-in (i.e. Transposer) because the native import, together with the new additions to C6pro would be enough to do anything you need that previously you could do with Poser. I always understood that scenes would not necessarily import flawlessly from P7 because of the SDK licencing issues though I have to say that I have not had any problem with shaders, the shaders that I have been using in P7 seem to have imported without problems into C6pro, the only issue that I have had is that the hair doesn't always render as well in C6pro (see enclosed image)
