The easiest way to remove it is of course an impact, but it sounds like you don't have one of those. Take your longest breaker bar (breakover), attach it to the bolt. Turn the motor untill the bar touches the ground ( you may have to use a cheater pipe if necessary ). Then just "bump" the key, don't start the vehicle, just bump it. Your other option is to get a chain wrench to wrap around the pulley, but be careful and don't damage it. Oh and don't worry about the tdc thing, unless your planning on messing with the timing.
