All that sounds fine, but the best advice is to hire a gun-friendly attorney. A lawyer will cost a lot more than that gun is worth, but he should help you decide if you have a case. Getting the pistol back is not important; it is not worth much. What you want is to avoid a conviction that would keep you from ever owning a gun again.
If it looks like you have a civil rights case, your attorney may be willing to take it on contingency (he gets a cut if he wins, you owe him nothing if he loses).
As to newspapers and TV, I assume this is in Illinois, where the press is overwhelmingly hostile to guns and gun owners, so a bid for publicity might backfire and make the police and officials determined to impose at least the death penalty if not worse.
Trying to fight this kind of thing alone is not a good idea. Officialdom has all kinds of people, some good, some bad, and some very bad, who will fight you, threaten you, even do you physical harm if you are too much of a nuisance. Get a lawyer.
