Need assistance in case.

This isn't a sufficient enough outline of what happened. It's just a bunch of buzzwords. Also not clear what your question is.

SHOULD I SEW FOR DAMAGES OR SETTLE WITH INSURANCE? IN EACH CASE WHAT KIND OF MONEY/TIME AM I LOOKING AT ?

Get a lawyer post haste.

I have gotten no where with the demand letter. I still do not know what bills were paid, which were not etc.

What's your question? This post makes little sense. Are you represented?

Do I have a case for dental malpractice?

Have a local med mal lawyer investigate.

Can I file a civil law suit against the district attorney for defamation of character?

You're being charged with a drug crime, you got dumped by a PD who was giving you (probably good) advice and trying to help you, and your best idea...

What is logical?

Is $3500 your max property damage amount?

Can you tell me if the school district and/or school is responsible for student safety to and from school?

On a bus, yes most likely. While students walk? Depends where.

Person made false allegation against me in a letter to my employer saying I had sexual relationships w students. What can I do?

Get a criminal defense and / or employment attorney.

Should I release my homeowners insurance payout limits to Lawyers for plaintiff in a dog bite case? I have no lawyer.

It probably won't change much if you do.

So the driver and the owner of the car, if different. I'd hire a lawyer if I were you; you'll do much better. A lot of firms, offer free...
