Our site now hosts about 40 of the best celeb mii's out there, and you can use it to follow links to other mii galleries. I love this stuff
For creating miis, step-by-steps don't work very well... much better to just use an example photo, choose the same features (it's always fairly obvious what choices were made, when you look at a Mii), and then tweak (eye size, position, facial expression, etc.) a little bit, to suit to your own taste... chances are you'll wan't to tweak anyway, so why spend the extra hour painstakingly following someone's blueprint for how many clicks they turned the eyes, etc.
Anyway, if anyone has anything they'd like to submit to the site, that would be great too!
