After exporting from Poser, place all the scene textures in the same folder as the exported obj. Bryce will ask where they are, click on the one it asks for, and it should automatically find the others. You WILL have to adjust the transparencey settings of any materials that have transparency, but that goes quickly. If you get an error while trying to import a Poser obj just open the obj file in UV Mapper, then save it out again. It WILL now open in Bryce.
