From your own post.

>776.013 Home protection; use of deadly force; presumption of fear of death or great bodily harm.—
(3) A person who is not engaged in an unlawful activity and who is attacked in any other place where he or she has a right to be has no duty to retreat and has the right to stand his or her ground and meet force with force, including deadly force if he or she reasonably believes it is necessary to do so to prevent death or great bodily harm to himself or herself or another or to prevent the commission of a forcible felony.<

So, why should this matter?
>1) Zimmerman failed to withdraw from physical contact nor exhausted all means of escape;<

The law specifically states you don't have to try to escape.

As to your other two points
>2) Was not actually in imminent danger of death or great bodily harm;
3) Initially provoked the confrontation when told to stay in the car and wait for the police.<

Since you weren't there, you have no idea whether he was in imminent danger or not. and
As has been said, numerous times in this thread already, he was not told "STAY IN THE CAR", he was told, "We don't need you to follow him". There is a difference.

And even if he HAD been told to stay in the car, the guy/girl at 911 is a flippin' telephone operator. Not a cop. A telephone operator. Has no authority of any kind to tell someone to do or not do something.
