ok i need some help i mad a custom char in the set up room but im haeing a problen its adding material zones that dont belong there how do i delete them  also how do i rename a material zone

I wouldn't do this in Poser, but then I never use the setup room for making figures either.

I would rename the materials in the OBJ in UVMapper.  I could also do this in Silo3D my preferred modeling program and could probably be done in a number of other modeling packages.

Also you may need to remove any unused materials from the CR2 file.  For this you could use a text editor, but I would use a specialized Poser File editor such as CR2Editor which I use or Poser File Editor 3 which is on my wish list.
