1) i would go with the semi-rigid insulation and cloth.
2) if you can tap off the output air from the iso box and flow it up around the speakers while keeping those boxes sealed, you're better off.
3) you need framing to hold the speaker box nice and solid. the speakers are decoupled from the box and not touching the face plate (but you ultimately seal around that). the boxes should (assuming you're ducting them) be sealed all around.
4) blue - loose insulation, green - hangers or loose insulation behind slats or other absorption/diffusion
5) you can do slats and hangers but if you don't seal the slats, they are not operating as Helmholtz resonators. you might make a slat box in the center section and make the lower and upper sections loose insulation for absorption.
6) i'd pick one side or the other below the stereo speakers for the sub and use your crossover/etc as needed to time align and set the actual x-over etc.
7) 10 degrees is pretty much maximum. so even though the 300's are "softer" than say ADAM or horns, you might try an experiment to set the speaker on a (crudely made lumber) stand (which matches the proposed height) to test the angles and see how you feel about them sitting @ 7 and @ 10.
