Well today I went to get my car inspected. (Gen 3.5 that I've had for a year now) I didn't pass inspection tho

, I wanted to ask you guys some questions and see if I could get some help.
1. One small light in the left taillight is burnt out, I just need some tips on taking the tail light off.
2. The main reason it didnt pass was because both CV Boots on the front axle are cracked and are leaking grease. I was wondering if there was a way I could tell (noises, handling problems, etc.) if the place I went is bullshitting me or telling the truth. And what could have caused this. Its gonna cost $373.

:
3. I'm at 108000 miles right now and the sticker next to the timing belt said it was replaced at 51000 miles. The guy quoted me $375 and then said I also needed some pulleys, and other crap replaced which would tack on another $350. Is this necessary? I know the timing belt changing is necessary but is the extra crap with the pulleys and all that necessary?
Thanks for all the help...I just don't wanna get screwed out of over a thousand dollars. I appreciate this guys.
