Pretty much the same way I have been doing it.  I am pretty impressed with how well Carrara manages to import Poser textures.

Quote -  The texture/shader import is an issue for all programs doing silly things like making things shiny. 

This is why Poser Pro was created - because it functions like a very expensive plug-in for C4D, Maya, LW and others. The Poser texturing issues get handed back to Poser to deal with during render while the host program renders the lighting and stuff. Vue has built a special importer instead. I don't think perfect integration between Poser and Carrara has been a super high goal for DAZ since Poser is A) a competitor, and B) inferior in many ways to Carrara's capabilities - many ways, not all ways.

The way I've handled it with Carrara is take a little time and customize an imported shader tree for each character/map. This usually has me making changes to a single texture and then subscribing to that one shader with the reference shader option in Carrara. Once everything is set, I drag my new character shader in the the browser and save it. Then when I have a new scen with the same character or clothing sets, I simply grab my replacement shaders and drop them on.
