At first you need to calm down. Believe me zbrush interface much much worse, so you need a bit time to understand how program work.
I think you also need to watch some video tutorials, i am recommend not official, they are too long with tone information what you do not looking. Old tutorials also work well, the main tools works the same except live clay was replaced https://www.youtube.com/user/AlienMinefield/playlists
The room difference only in tools panel (but you can even change that for any room), all visibility in types of model like object paint, sculpt tree, etc, you can open their windows in any rooms and switch visibility.
You do not need anything to export in most case
The second would be better if you showing screenshot for every problem.
