I'd like a brief, easy explanation about securing the rights to a written work; I would look it up, but it may be easier just to get a quick, easy answer from someone here.

I understand that copyrights are for art, literature, films, and all of that sort of stuff, and that trademarks are for names/symbols and the like; so, does that mean you can copyright the book itself and trademark the title (To be used in future books/whatever)? And if you copyright a book, would you have to individually copyright each related book (In other words, sequel?) And, if you do copyright the material, does this secure the rights for all media adaptations, or is it possible to secure the rights to each potential future media adaptation individually? And how does submitting work to a publisher work in to this?

I'm pretty much clueless as to how this works. Any explanation would be greatly appreciated.
