Need some help, went in for oil change and now im looking at this!!!!

[mikerx5]

As the title says dropped off car for oil change on 04 3.0 and my guy just sent me email saying this is what i'll be needing soon....

First main concern is the intake boot for the engine is split open and will cause the check engine light to come on-$179
Front brakes at 3mm (min spec)-$758 (pads, rotors and sensors)
Thrust arm bushings cracking starting to thump when brakes are applied-$371
Rear brakes at 4 MM-$255 (JUST NEEDS PADS AND SENSORS)
Recommend power steering flush and brake fluid flush-I will review this on the phone or when you come in
Drive belts cracking a little not too bad-$203

now, this car drives perfectly fine to me but at the same time i obviously dont want to have serious problems.... what would you gentlemen and ladies suggest be the proper course of action - MUCH APPRECIATED.
