I would advise crating a new, empty folder for your projects - even one per project if you work on more than one at a time. Add that folder to the DAZ Studio Content Directories list. Place your textures in that folder, in RuntimeTextures, before applying them to your model. Save the figure asset to that folder, and make sure that the Base path in the options dialogue is also set to that folder. Save your presets there. Add a readme, and zip the folder up - it should contain all and only the files needed for your set.
