When you have your car in for service... don't forget to ask for new wiper blades and a new pollen filter. They should be covered for free. I would also have them check for any open recalls on your car. (see battery or seatbelt insulation recalls)
As long as your car tracks straight and the steering wheel doesn't pull(especially under braking or acceleration) I would skip on the alignment. Your car next year will most likely need new tires, I would do the alignment then.
