You may want to consult with an attorney to handle the speeding ticket separately on this. There are many good lawyers who handle traffic matters successfully in WA state and you may be wise to try and get rid of this speeding ticket which could point toward your fault. If you bought the rental car insurance, that should cover this situation, and if not, then talk to your own auto insurance company about it. You may just have to wait and see what the rental car company tries to do with it.
I agree with Mr. Kelly. It may be necessary to look at the other driver's auto policy language to see whether there is coverage on this new vehicle. You can complain to the insurance commissioner, or you may potentially have a bad faith claim against the other insurance company.
I practice more in Oregon than in WA, but in OR, there is an online child support calculator where you can actually calculate what your child support would be. WA may have something similar, but I'm not sure. Try googling Washington child support. The answer to that is usually highly dependant on you and your wife's incomes, who provides insurance, who pays for child care, and sometimes how much time is spent with the children.

You may be thinking of something similar to a common law marriage where the law in a few states recognizes a couple as married if they live together long enough and hold themselves out to the community as a married couple. Common law marriage doesn't exist in very many states anymore either, but there's no similar rule for divorces. But since you haven't seen your husband in so long, I can't...
You did the right thing by contacting your homeowner's insurance co. You pay for homeowner's insurance for events just like this. Just keep in contact with them. Should the case get so far down the road that end up being sued by this other person, you will have an attorney assigned to your case that your insurance company will hire. This will save you a lot of $ in having to hire your own attorney. Obviously, if your preference is to hire a separate lawyer, you may do so, but legal counsel...
How speeding tickets are handled depends largely on the court you're in. I practice in WA and OR, and even here they vary by court, county, state, etc. I would say call the court clerk and ask what their procedures are. If you can get it reduced, there's no harm in asking. You might also ask if there is a traffic school option or deferral available to avoid the conviction.
