Making water changes during a cycle will stall the cycle, you should really only do water changes if the ammonia or nitrite levels get dangerous. If you do the water changes for no real reason, your cycle will take much much longer.
I wouldn't add ammonia to a tank with a fish-in cycle. It will make the nitrites spike even more, creating a dangerous situation for your fish. You want a light bioload when you cycle, light bioload will make it safer for the fish, reducing your chances of needed to change the water, and reducing their likelihood of dieing and stress. Once you go through your light cycle, add fish gradually, you will most likely see a mini cycle every time you add fish. Try not to add more fish until the end of each mini cycle.
I used to have an excellent article on cycling, with a chart to chart your levels on, and a graph to tell you what to do if the levels get too high.... I'll try to find it for you.
