Tinting price depends on where you go. If you live in the SoCal area send me a message and I can refer you to an excellent tint shop that will tint 5 windows for $110.
Be aware of bad tint jobs. I've had friends that have gotten bad tint where it is dark on both sides inside and out. It makes the car incredibly difficult to see out of at night.
As far as taillights it depends on what kinds of lights you want. They will vary in price from $150 to over $300.
