Character Profile Questionaires

I have heard a lot of writers talking about Character Sheets. So far on my NaNo novel, I have two main characters sitting pretty solid in my head. I really don't want to sit down and do a profile on each. I would rather let them form a bit more on the paper before I go filling out a "demographic" for them. Maybe afterwards, it would be interesting and give me some different directions to go in if I get stuck. On the other hand, I think I will fill in partial sketches on some of the lesser people that could be in my story. I'm a real visual person, so I've been cutting out any interesting people pictures from magazines and taping them in a notebook where I can write whatever I want alongside them. I think that may come in handy at some point too.
Below are links to some character profile pages:

Rich Hamper's Character Profile Sheet
Character Sheet Generator
Charlotte Dillon Character Chart (with questions after to ask your character)
Writers Write - How to create a character profile
Fiction Writer's Character Chart
Gotham Writer's Workshop - 2 questionaires
Character Trait Chart and Personality Components
Fiction Addiction Character Creation - multi-paged

I haven't decided which one(s) I will print out yet, but it was interesting looking through the questions. There are different ones on each. Some are very in depth. Some I wouldn't have thought of at all. In answering, I think you would definitely get to know more about your character. And with some of those in depth questions, maybe TMI (too much information) haha!
