devonthink advisor - mac consultant -- 2

Hello, I have few questions, which I would like to discuss : How do I set up my database for my purposes. I am constantly referencing, editing, and highlighting multiple documents at one time. I don't know how to organize and setup my database and coordinate/sync it with my Mac OS file system - What is the best way to title, tag, file, label, rate, and flag files - I need some examples and organizational rules because my database has very quickly become disorganized and I am losing files - What is the best way to pick and document a few quotes out of articles I'm reading? I don't know how to do this then find these quotes when I need them... perhaps in the "Annotations" box?
