If you are going to tackle this bring your car to a shop and have them break the crank bolt free for you. Even with my airgun I always need to go to a professional shop first to break that damb bolt off.

And as mentioned above, have someone that has done this before show you. I have done two timing belts/water pumps on Hondas and each time I am nervous that I will mess something up no matter how carefull I am. One small mistake could cost you a lot more than having the dealer do it.
