I've an almost-4-year-old T61.  I haven't noticed screen brightness
decreases, but then I never use it outside.  IIRC it wasn't very usable
in sunlight even it was brand new.

There used to be a bug where the dynamic range of screen brightness you
could access from Linux was cut in half if you booted while on battery
power, and the BIOS setting for display brightness was set to power
savings.

You may want to try adjusting BIOS settings and/or rebooting with AC
power plugged in before ordering new parts.
