Front wheel bearing on a '01S

[Frodo]

Okay, I have finally found some time to dive into my front wheel bearing job. Haven't gotten too far...at this point, I have the wheel off, as well as the brake caliper and the rotor.

I'm a bit confused as to what's next. In that I have the SIR bearing/hub tool, I am inclined to do this without removing the wheel bearing carrier from the car. I have Wayne's 101 Projects book (which is a good book), but he just mentions that this can in fact be done on the car. It's not real clear to me just what needs to be disconnected prior to jumping into the bearing removal with the SIR.

At the stage I am at, what exactly has to be done before I start removing the bearing?
