Welcome to the forum!

Sounds like rather than just putting a water pump gasket on, you should consider replacing the entire water pump. While you have the cooling system drained, replace the thermostat as well. Test the pressure cap and replace if necessary. Make sure the cooling fan works properly as well.

As for the power steering jerking, have you checked the level of the fluid and listened for abnormal power steering pump noises?
