I was too lazy to read the whole thread but since I make 3d i thought i'll chip in. so:

1) For modelling, go Blender, it's the industry standard, there's tons of youtube tutorials and it's free.

2) For posing actors and arranging scenes, only DAZ3d Studio. PoserPro is weird, has little content to buy and it's rendering engine is sh*t compared to IRAY which is built in DAZ.

3) Someone mentioned a website with pirated content for DAZ… well, that's not really an elegant way to do this, but you can at least download some stuff and try them out - if everything works as expected and you like it, just pay for it later.

4) Figures I use: Mostly Daz Originals (so Victoria 8, Bridgette 8, etc…). They are the most predictable and compatible with clothing and stuff. I avoid anything that's not Genesis8. Also, be CAREFUL when you buy aftermarket figures, a lot of them have broken mesh topology, weird textures, and so on… I only use adult models.

5) For genitalia:
- New Gens for Victoria 8 - don't get fooled by it's name, it's compatible with almost all Genesis8 figures (not only Victoria) and looks really great

- Golden Palace - also nice but I prefer New Gens

- For shemales, Futalicious:

6) Scenery: god there's too much of it, just do your research :P Most scene packs on DAZ store come with props you can arrange in your own way etc etc…

7) For extreme/dolcett stuff:
- Davo's Hell's Kitchen
- Davo's Cannibal Kitchen

ugh… making 3d porn is such a broad topic we should have a separate section for that, not just separate thread.
