Let's rate different marketing methods

With a month left until my debut novel Kingdom of Rage comes out, I've been obsessing about how to market it outside of my little circle of friends and coworkers. My top choices are:
1. Before it comes out, do a "Launch My Book" campaign where people take a photo of themselves with the three words written in a creative way, the winner receives a free signed copy of the book plus a $50 iTunes gift card.
2. After the book is for sale, people take a photo of themselves reading the book, and some gift for the winner.
3. Do a book signing, create a press kit, etc.
4. I'd like to throw a party of sorts in my hometown, with food and the works.
Or, I could do all of the above. Nothing I've said so far is new, however, there isn't much out there about what works and what does not.
People have the attention span of a flea. I blog and update FB on a weekly basis, but I never receive any comments or feedback. I don't want to waste my time doing things and spend money if the turnout is poor. I'm living paycheck to paycheck and cannot afford to buy food and books that just sit idle.
So, how do you get people involved and excited?
I'm not at all afraid of public speaking and I put 100% of my effort into things that I care about.
Thoughts?
