February 2000 Fire

I have a 99 pontiac grand am gt with 72000 miles. I have had several issues with the car. First, (at approx 50k) the coolant light came on, I took it to firestone and they had to replace the water pump and the serpentine belt. The brakes grind and I had the pads/rotors checked and they check out okay? Occasionally, the car will sputter under acceleration for no reason. The coolant light came on again at 71k and now the gasket has to be replaced at my own cost.
