Calorimitery and the First Law of Thermodynamics

I recently performed a lab experiment dealing with the properties of a coffee cup calorimeter.  One of the procedures involved measuring the temperatures of liquid water in 2 coffee cups (1 hot water, 1 cold water) for 3 minutes, and then mixing them into one cup and recording the temperature for another 3 minutes.  I have several temperature measurements, but I am not sure how to use that data to calculate "heat lost by warm water" , "heat gained by cool water" , "heat lost to calorimeter" , or "water equivalent of calorimeter."  Please see the attached file to view my data, but I am mainly interested in how I would go about filling out the "Data/Calculation chart" at the bottom of the page.  Thanks!
