Ok.  Keep your BIOS up-to-date.

No, that interface is unrelated to thinkpad-acpi.  However, it could be that
the video driver in your kernel is a bit old, and buggy.

You shouldn't need to do anything, it handles it automatically on an
up-to-date BIOS and kernel... IF it works.

If it doesn't, you can use acpid scripts to call xbacklight (but do not load
the video mode in that case!).
