If you export the items from Poser in FBX and I also think Collada format they will create a texture folder that if they are saved in the same location when you import them into Blender it should grab the textures automatically the only hiccup that happens sometimes si the textures might get applied upside down due to Poser Y is the horizontal Axis and Blender that Axis is Z same thing use to happen with Zbrush textures in the past.
