Yeah, sometimes you have to just learn by your own mistakes!! Its the only way to fully understand why things only work if they are done a certain way. Really pleased with my latest panels though and my carpentry in general is getting much better - I built a shed from scratch in my back yard last week!!

More absorbing material inside the cavity will dampen it acoustically, i.e. will lower the Q factor (broaden the band of efficiency around fc).

1/8" plywood will treat deeper bass than 1/4". Chances are that you'll need to cover many corners and surfaces. But you will need to EXPERIMENT, because real acoustics is not an exact science!
This is what I thought. I totally get the physics here. The thinner the plywood, the more 'give' it has to 'wobble'. Though I would have thought that the screws wouldn't want to be too loose or else the air-tight seal won't be as good.
