Hey there Mike... sorry to hear about your experience with the tar. I can relate... it frustrates me to no end when they spray a road, and then open it before the tar has cured. I've never experienced hot tar, and I'm not sure just how you were able to drive on a section of road that freshly sprayed. The tar will generally cool pretty quickly... but that wasn't your question.
I have had great results with a liquid wax from The Wax Shop, called Super Glaze
http://www.waxshop.com/ It is a Carnauba-based wax, with a solvent based agent to keep it liquid. The solvent works wonders on things like tar, gum, adhesive, etc., and the wax protects the surface. If the paint is truly burned, the Superglaze may only take off the tar, but not help with the paint. The Wax Shop also makes a very mild cutting agent for paint cleaning that works great on headlight and taillight lenses. It is called Safe Cut. I regurlarly use either that, or a mild cutting agent made by 3M on my own headlight covers to keep them from dulling, or yellowing. One of these may help your taillights.
Hope this helps.
Bill
