there are really two main causes of "squeal" in brakes.
1. Wear. when the wear-pads get into the rotor. Though I've never described this sound as a squeal, that's what brake mfr's usually call it.
2. Vibration & rubbing of hard parts against other hard parts. This is why the paste is used. This is also why the backing pad is there. Both are designed to provide a "separation" that will resist the vibrations transferring through. You'll notce that the factory pads (and some of the aftermarket pads) for this car have "counter-weights" on them, sorta hangin' in the breeze.. these are dampers, designed to cut that vibration as well. This is the primary reason that the Raybestos race-pads some of us are using are so damn noisy, because those weights aren't there.
So: paste or no paste? ideally, the pad provides the same protection as the paste. so maybe some redundancy in using both.
But I ALWAYS use paste. I use it on all of the sliding parts, adjusters, etc as well. It keeps things working smoothly.
YMMV
