Toyota: 1997 Camry Car Shakes - Spark plugs?, preventive maintence, toyota dealership

Question
I have a 1997 Camry with 123,000 miles on it. Last week I was driving my car.  I came from a cold start and drove through my neighborhood about five blocks.  Then I pulled out onto a major busy street.  After turning onto the street my car began to shake and make a noise.  It didn't loose power but I felt as if the whole car was going to fall apart.  I drove it a few more blocks and stopped.  I took it to the Toyota dealership and decided to have the 120,000 maintenance and see what was wrong with the car.   Well, they came back with a long, long list of things that are supposedly wrong with my car.  And I guess they said it was the spark plugs needed to be replaced.  What do you think?  

Answer
Lori, feel free to copy that list down if you'd like:)  I wouldn't mind reading it to see what's actually a good thing and what's just Toyota "preventive" maintence.  As far as the car shaking, it could be the engine's spark plugs but let's think simpler first..  At 120Mi, your motor mounts should defintely be checked.  Over time, they tend to wear these mounts and eventually, once they go, the vibration they would absorb doesn't get absorbed by the rubber but rather by the car itself.  So, that's my first recommendation to you.  After that, a good tune-up wouldn't hurt.  Let me know what you decide to do!

Hope this helps
