Sounds like a trip to the Texture Room is needed. It looks like Carrara did not build a shader tree with a layers list; a seperate multi-channel shader for each material in your import. I seem to recall Carrara has some trouble looking past the first directory it finds a texture map in, so you may need to instruct it where the clothing and hair maps are located. You are going to spend a little time with the manual here; the Texture Room is pretty simple once you get the hang of it but it isn't something I care to instruct about in a single post. Another option is to try different import options. I seem to recall that "as vertex primitive, create a single polymesh, create only one object" worked very nicely for bringing a Poser character into Carrara 3 demo.
