That's pretty much it - but it's a specialty tool.
A "power steering pully puller" actually grabs the flange around the hub to pull the pully, which allows it to come off without being distorted. I believe Autozone will rent one out, but I usually just buy stuff like that - I'll need it again! New/reman pumps don't usually come with a pully attached... And, the tool only cost me around twenty bucks.
You can't use a three-jaw puller or anything like that on these pullys - it flat won't work.
The installer is even easier - it should be a screw that threads into the hole in the hub shaft (5/16"-18 or 3/8"-16, I don't recall which,) a couple of flat washers, and a nut.
I find it easier to use two washers (and grease the surfaces where they touch each other) and to paint the hub shaft with never-seez before you put the pully on. Makes it go on a little easier, and helps it come off for next time...
