Certainly can't hurt to have the heat shield with ceramic coated headers - I have both.

As for checking/filling the clutch master cylinder, I can see the level if I stand next to the car and lean over the fender. To fill/flush, I bought the smallest bottle of fluid I could find and again leaning over the fender I can top off. I just keep refilling this little bottle and keep it just for this purpose. It takes some getting used to which way to bend/pour since everything is upside down at that point, but you'll get the hang of it.
