Bell curve problems

How do you develop a bell curve for 1,000 cases:
With a given mean of 20 and a standard deviation of 2, how do you compute the -3,-2,-1 (mean), +1,+2,+3 points along the baseline of the curve (assuming the curve is normal)? Then repeat the mean of 10 pounds and the standard deviation is 4.5. Repeat again with a mean of 4 seconds and a standard deviation of 2. Now how do I determine the number of cases that fell in each standard deviation division for the distribution of the 1,000 cases?
