Everyone has given you a lot of great suggestions.

One thing that I can add is to look for a digital camera with a LCD screen that swivels so you can see what you are shooting. This allows you to either raise or lower the camera when the situation warrants. Keeping the camera low hides the fact you are taking pictures and allows more candid shots. Raising the camera high and shooting down helps when you are in a sea of people.

Additionally using the LCD screen a lot really eats batteries. Bring at least two extra batteries with you for a days shooting. Another battery saving tip is to keep the auto focus off continuous. Allow the camera to focus only when you depress the shutter release.

My camera is a Nikon 5700. A great camera for the price.
