DAZ3D - Beginner Questions

Hi everyone,
I just got DAZ3D recently (yesterday) and I already tried some stuff here and there and watched some beginner tutorials. But otherwise I'm a complete newbie when it comes to 3D and rendering.
But I got some questions and I hope you can answer them.
1. What's the basic stuff you should get to create some good renders?
2. I often heard that I should get a figure called Victoria 4. But the first question I got is: Why? I mean DAZ already got his own figures, what are the advantages?
3. Where do I get the adult stuff. You know, the stuff between the legs, are these already included in some figures?
