As Newbie said have a good look at teh examples of the time library so you understand how timekeeping kan be done. To learn this an LCD is usefull so you can follow what the program does (As it is a write -only device it can be removed when everything works.)
For the pins you have to use PinMode() and DigitalWrite() , see for examples : http://www.arduino.cc/en/Reference/pinMode
As you are new to Arduino it is good to go through the tutorials http://arduino.cc/en/Tutorial/HomePage and reference pages http://arduino.cc/en/Reference/HomePage and try to understand the examples. Yes, it will take some time and your Arduino knowledge will grow step by step and will have a solid base
