YACT: Tune up time

[Plasdom]

Honda civic, purchased it 3 years ago and never done a tune-up. Change the oil on time though. I think I also need an alignment and balancing. I have a firestone coupon for $150 tuneup and alignment/balancing. The local jap garage wants about $200 for just a tune-up. What is done in a tune-up aside from chaning the spark plugs anyways?

change the air filter, just follow the maintenance schedule in the manual unless something urgent comes up.
