Yes. This would make us independent from the BIOS boot mode.

Maybe - would be nice if this would work, but not required.

No. We put in a disk that is already ready to use.

Linux. 32 bit (and 64 bit if this alternative is possible). Vanilla kernel +
Linux from scratch.

Linux - as written above 32 and 64 bit but not at the same time of course. So
one image for 32 bit and one for 64 bit. No boot option to choose.
No Windows, nothing else.
