Putting the trans in reverse (you may need to block the wheels also) is your best bet if you do not have a impact wrench. I would not try turning the engine over with a bar on the crank bolt.
Yes you will need to tighten the bolt the same way you took it off. Below is a pic on how the cam and oil pump sprocket are aligned. The crank needs to be set at TDC (top dead center).
