I don't use Poser as much as other apps, but there are a couple of things that are important for good renders regardless whether you use Poser, DS, or Maya. Like others have said;

Lighting, lighting, lighting - that is the most important thing. Without good lighing the best modeling, textures, and posing work in the world will look bad.

Morphs++ and a good texture set for V4

Save your money until you understand Poser little bit more know what you really want to do with it - Only buy stuff that you WILL use. I'm sure there are some great products out there to help you on your way, but it's easy to buy more than you need.

Oh, did I mention lighting?? You can find a lot of help here by searching the old threads, and by asking new questions. I'm still fairly uncomfortable with the lighing in Poser, but I can say from experience if you keep learning ang trying, ramain patient, eventually you will get the results you desire.

Good Luck!!!!
