Changing the ignition coils on a nissan altima 05 question.?

My girlfriend has a 05 altima, 4 cylinder. The dealer wants 890 dollars to change the 4 ignition coils. I know I can do it for about 300(parts). Question is, do I need to have the computer reprogrammed after I do this or is that not necessary when changing the coils? I will also change the plugs while I'm there. Thanks
