I Just Purchased 4GB Memory And Would Like To Know If I Can Easily Install It Myself Or Should I Have Apple Install It? If I Can Install Myself Can I Get Step By Step Instructions? Thanks,

Its fairly straight forward and you should have no problems doing it yourself as long as you follow the instructions.
