Tutor, after rereading your post...are you saying CC is a standalone product but you must purchase iClone to get it because it works within iClone?
You can't purchase CC by itself, you have to buy iClone, but you can get a free lite version that is actually standalone but limited?Character Creator is a standalone program but it is included with an iClone 6 Pro license and requires iClone to function. I have never tried CC Lite (no need to), but it seems than that it can function without iClone, but with the noted restrictions.
I'm trying to think about your pipeline, and I believe you can do what you want to do without 3DXchange. It is relative easy to create morphs that will change the shape of your character and that is something that can be done with just CC. Customized clothing is possible but complicated (at least that what I find), so I would stay away from that initially.
You can export from CC as iAvatar, and that can be imported into CT8. (I had never done that but it works.) You will need the Pipeline version of CT8 to be able to do this.
I've been told that Go-Z will be implemented in iClone at some point, so that would give you an even easier path to Z-brush. As you will have noticed, a new release of iClone is upcoming, so what features will be included and when is still sort of open.
Currently, CT8 Pipeline is also required to create faces from photographs for CC (that may change at some point), if that is of interest.
I wouldn't want to advise you incorrectly, so I hope others will chime in.
