Howdy UNK,
I'm curious as to what state are you located in? Nearly every state has some type of tint law that "limits" you to what you can put on your windows. The reason I put limits in quotes is that some states, like California, are really strict on their tint laws whereas others such as here in Texas aren't super strict on their laws and enforcement. I would look up your states laws to get a range of tint you want. I would say most states you can get away with 20% if you wanted to go a little darker. Personally, on your car, I would 20% regardless of what the tint law is.
In regards to your second question, I would visit the two links below that best explain how radar and laser work. A lot of radar detectors are fairly close when it comes to range but differ in features they offer the consumer, such as the Valentine 1 has arrows and a number counter while the 9500xi has radar detector locations. It's all going to depend on what your looking for. I would venture to say that the two most used radar detectors are Escort and Valentine. Let us know if you have any other questions and I hope this helps
