chroot_* influences what ends up in the filesystem.squashfs (aka 'the
live system');
binary_* influences what ends up on the iso image (aka 'the live cd').

add the boot parameters to LH_LIVE_BOOTAPPEND.

in general, rather than replacing complete files, you better automate it
by editing them through a hook.

if you decide to completely replace them with an own file,
chroot_local-includes should do the trick.

a file put into:

would get installed to:

in the resulting live system.

yes; however, in general, you would only put those selections into the
file that are overwriting default behaviour of debian - this way you
keep the preseeding file small and better maintainable.
