I always love the iFixit guides, this is another good one.
I agree with those who wrote that this guide is a bit overkill to just change the connector, though. There are videos on YouTube that - although nowhere as good as the iFixit ones in terms of video/composition quality - show you how to remove the connector in few, easy steps without removing the logic board or the battery. Much easier, IMHO.
The rubber casing around the microphone, the grounding cable from the edge of the headphone jack and the the plastic gasket between the headphone connector and the outer shell. Those three elements are all correctly mentioned in the guide, but not in the Video.
Finally: the hint about removing the dust/lint from the connector is priceless: it didn't work for me, but I can see how it helped may others... it should be put at the beginning of the video... I know it might take away some $$$ from iFixit, but it would help a lot of people and at the end build more trust and more loyal customers for the future.
