You should use the rubber blocks to absorb the vibration. Rick's sells small aluminum servo plates that fit over the blocks to make the servo more solid while still being protected from vibration.

If it's like my R50V2 it came with ali mounting plates for the servos.

You should use the rubbers for the servos, to absorb vibration, but not the brass grommets.

You gotta use the rubbers for extra protection Even with the ali mounting plates you need to use the rubbers to stop the servo being damaged internally by vibration.

Saw about not using the brass inserts on raptortecnique. I pressume it's to do with vibration (being transmitted through the insert?), but I remember a thread a few months ago where people had used with and without. Both seemed OK I recall. I'm running without at the moment.

I don't use the brass inserts either, they aren't needed.

In some older 9252 servos the TT servo screws were a very tight fit, in the latest servos the inserts are a larger diameter. So I use inserts and the ali plates.

The brass inserts also lock the grommets into the tabs.

Yeah, I agree. The brass collets are part of the screw, and basically hold the grommet, and prevent the grommet from being compressed excessively, which defeats the shock absorbancy. If you've done things correctly, there is a uniform rubber cushion between mounting screw/ collet and servo lug.
