Sorry you are having issues with our documentation/products. We are working hard to fill in the gaps that customers are experiencing, but with the number of products we are having to support, things do sometimes fall through the cracks. We are confident that we are heading in the right direction, and you should experience less issues in the future.
If you haven't seen this already, you may get some ideas on how you can use all the products in your suite from the Web Dev Workflow here. web-dev-workflow.php.
In regards to the How to Adding Custom divs using CSS Sculptor tutorial, this was written for CSS Sculptor 2 and is listed under Archived Documentation for this reason. The concept is the same, but like you said, the UI and process is somewhat different.
If you have specific issues in accomplishing something, create a new thread on the forums to get help in accomplishing the task. There are a lot of people on the forums answering questions, including our Support Staff, and you should get help pretty quickly.
