Good luck.  You will need to invest more time with DS especially since they are trying to move away from Pre-Genesis 8 models and concentrate on G9.  You will need to invest in clothing and pose scripts to convert those files to G9.  In either case, whether you continue using your present content with Poser or invest more time and effort in learning a different app, you will need to realize that tinkering under the hood will be the only way to get satisfactory renders and images.  

Again, good luck.
