You can always export an object from Poser once you have it how you want it and then run it in Daz without going through the morph conversions, but it will be a static object and not rigged.
Also sometimes you have to tweak the textures to get them to render correctly. Generally they come into Daz with a plastic stetting which you need to change to matte or skin and then turn down the gloss or you get some rather odd reflection artifacts especially around the eyelashes. For Iray if they have SSS mats then you need to sometimes put like 128 128 128 color in the diffuse slot or it will blow out your model and it it will render very very light. Iray doesn't particularly like spec maps as that is kind of built in so you may have to put the texture map in the spec slot or just disconnect it if your textures come with spec settings.
