Well it was my father-in-laws before it was mine. He traded up for a new Maxima and pretty much gave it to my wife and I. Given that he would run the car to the doctor everytime it had the the perverbial runny nose, most of the list you mention has been replaced. Even the transmission was replaced on his extended warranty. Not really certain about the fuel rail/injector O rings but I will check on that.
Welcome to the site! Although I drive a 1996 with the 3.5 liter I've heard that the 3.3 is a great engine that is really durable and dependable. I know someone that has an older Grand Caravan with that engine that has 180,000 miles with no problems yet. One of the weaker points of these cars are the transmissions. They aren't bad if maintained properly (regular filter and fluid change along with the periodic flush).
Enjoy your time at DI.net and best of luck to you with your fine American automobile.
