Baker seems really fit for this, your way of working sounds right. You have to have your UV mapping right to make any sense of the results of baker OR converted procedurals. I have used it that way, also in combination with UV Mapper to get the positioning right. Oh, by the way, Poser 6 does not import everything yet with TransPoser 2.0. But if you want to stop spending money, you might want to check out UV Mapper first. It helps you create UV maps, which you can export, and the model with those UV codinates that you can report in Carrara. The baking of procedural shaders may not have to be necessairy. Just build the textures in Photoshop. Good luck!
