No need to draw circles, just mark a small x to center punch from. Establish socket mounting holes with the socket itself after chassis punching the hole. Yes. And that space between the two extrusions gives the chassis some character and keeps it from looking like a "dull and boring" slab of metal. Rather the same as the three big holes in the Evett & Shaw Flatte amp. By the way, the blue sandwich between the acrylic slabs is a nice touch. You've got a good eye for design.

It depends on the texture of what you're gluing and if you're gluing metal and don't use a super hot glue (or heat the metal) you'll get a crap bond. If it's two smooth surfaces, crap bond. I have glued a relay to a 65°C chassis and broke it trying to remove it. I've also had what you describe - a weak glue joint.

If the input jack is grounded on the chassis and the amp is also grounded on the chassis then right, you shouldn't also have the shielding making a second path. So if you have a switch mid-way, I'd ground the shield at the input jack, but not at the switch and for the leg after the switch I'd ground it at the amp but not at the switch.
