w00t for characters and plot! I have those, too (thank God), even though there is a new plot-bunny gnawing on my brain that I will ignore. Setting ... well ... I have no idea what you could use as a setting, since I don't know where your story will be going. My characters are going on a holiday. :P
If you want to add me as your writing buddy, my name on NaNo is "bananarama".
