If purchased from the Market then the best way is to open the market, touch Menu->Downloads. Find the app, touch it and touch Uninstall. If you are referring to built in apps, they cannot be removed.
You can also go through settings-->applicaitons-->manage-->Scroll to the app you want-->Uninstall. I have installed a great app called aTrackDog. I can easily open it & uninstlal apps quickly.
