The decision to go to war is in the hands of our elected leaders. We assume that they aren’t going to lie to us to get us into a war. But assuming that they do not lie to us, and we have time to evaluate whether a war is ‘necessary’, how much say should the People have in the decision to go to war? Once we’re in, how much say should we have in the decision to stay in?

As a general answer to your question, the people should have absolutely no direct say in these matters whatsoever. That would be the equivalent of mob rule, there is a reason that decisions of this nature are made by 536* elected officials, not by the populace of the country at large. Often times the strategic interests of the United States cannot be intelligently analyzed by the common man, sometimes the geopolitical ramifications of going to war or not going to war cannot be properly analyzed by the common man. They often cannot be properly analyzed by the President or Congress, either. That’s why there are Congressional committees which regularly meet with experts in military and political affairs, and why the President has at his disposal more professional advice-givers than any other single person on the planet.
The decision has to be in the hands of our elected leaders. Our role as citizens is basically to support our elected leaders in their decisionmaking by voting for their reelection, or to show our lack of support for the decisions they have made (and the ones they either say they will or can reasonably be assumed to make in the future) by voting against them. That is not our only role, however. As elected representatives our congressionals representation is responsible to us, and we have an obligation if we feel strongly about a current political issue to make our feelings known. If we strongly oppose the decision to go to war, we have an obligation to write letters to our leaders, to stage protests, and et cetera.
There should certainly never be a “referendum” on whether or not to go to war. I can think of many cases where such a referendum would either be counterproductive or would not have changed the end result.
The War of 1812 was a war that most will agree in retrospect we probably should not have started, but I think given the political climate of the times and the power of the War Hawks in Congress any sort of referendum on the war would almost certainly be approved. The same goes for our war with Mexico.
The American Civil War probably would not have been fought if we held a referendum on it, which I think would have been disastrous for the United States. The Spanish-American War would almost certainly have been approved by referendum. World War I probably would not have been, and World War II almost certainly would not have been any earlier than Pearl Harbor, after that it’s all but certain it would have been.
I also think that in the case of a situation like World War II or the Civil War where the Presidents in question were more than willing to fight but the populace much less so, outright lying and deception by the elected leadership to push to populace to war is more than justified and even required. As well as taking firm executive action to begin waging war with little or no regard to the greater debate at hand.
