TIMER2 is 16 bit so prescaler 4 wont fit in it. you have to change it to prescaler 10. If you press the button for 3 seconds, LED will glow, what happens if you did not release it and continue for 5 seconds? should the LED that started glowing after 3 seconds turn off? anyway, i have modified your file and given you a template. This will let the LED glow if you press the button for 3 seconds and will turn of if you press it for 5 seconds.

I did not see anything wrong with your main file. But I did not see anything related to buzzers as well. It will be helpful to if you can send me your full project. Also you are allowing your TIMER2 to overflow, what interval do you want on your TIMER2? is it CC[0] or CC[1]. You have to enable the short to clear the timer with one event.

Take a look in the register description for Timer COMPARE0_CLEAR - Shortcut between EVENTS_COMPARE[0] event and TASKS_CLEAR task COMPARE1_CLEAR - Shortcut between EVENTS_COMPARE[1] event and TASKS_CLEAR task
