Two things I'd like to add for anybody about to do this job:

First, my coils needed cleaning on the insides pretty badly, where the metal contact the the plug is made. Damp Q-tips worked very well for this. Here is a before and after pic



And second, this tool makes grabbing the plugs out of the engine a breeze. I would highly recommend getting one of these, which has a claw on the end, or a magnetic one will work too.

If it's a 6 sided socket its a 15mm, if it's a multipoint socket its a 14mm. I forgot to mention the thing to grab the plugs from the head. Good call
