Impossible choices are always good too. Does the hero save his/her most beloved or everyone else? (they did this fairly well in spiderman) Those type of questions can also push the protagonist into evil or insanity which is always fun. [img]smilies/wink.gif[/img]
littlemanpoet, I like your types of bad guys listed. The only other I can think of is the real behind the scenes guy that they only find out about much later. I can't think of a Tolkien parallel though.
Generally the protagonist and antagonist are the two people that will be affected most by whatever the theme of the book is. They're the ones that have to most to gain or lose. So often they're connected, like Naaramare has it.
Goodluck with your story!
