You want to know special tools, but maybe if you let us know your mechanical abilitites. You will need all the regular tools, plus breaker bar, torque wrench. You will need to know how to put the brakes back together, and bleed them.
I have found on a high milegage car, if you pull the front hubs, and you have high mileage on the half-shafts, if you don't replace them, after you put the new bearings in, the boots on the half-shafts tend to fail soon after, if they are high mileage, simply because fo the flexing they will be put through while you work on removing and replacing the hub. You may not have half-shaft boot failure for a few months after the work on the bearing/hub.
Also, to pull the bearings and races, there is a clip in there which need to be pulled to press the bearings out. I don't remeber if I used a special tool to pull the clip out, but it's hard to do.
If you don't take them to a shop to have them pressed in and out, you wil need a 5 lb, hammer to beat them in and out, and it is a very hard job. So, have a shop do it like others have said.
I also have to do this job again because I neglected to do the right side while I did the left side wheel bearing. It has slack in it. Don't pull the hald-shaft out unless you plan on replacing that too, or you wil need a new Seal where the half-shaft goes into the trans.
You will need some high temperature wheel bearing grease for the bearing. They come pre-greased, but having more on had is imporatant because when you put the bearing and races in you can lose some of the pre-lubed grease. and before you put the seals in make sure there is plenty of grease.
I also used the Loaner Tools from AutoZone (autozone.com ) for pulling and pressing the bearing seals.
You can buy a whole kit which includes the hub and bearings, but you shouldn't need a new hub, unless the old one is damaged. It's pure hell pressing the old ones off and new ones on without a press. You have been warned.
Have a shop do the pressing of the old and new bearings.
While you are doing them, might as well put new brakes on if your brakes are more than 1/2 way through their life cycle. And you plan on keeping the car. get high quality brake pads. Don't skimp. The cheap ones suck bad and wear out extremely fast.
If you are not experienced and don't have the time for this and don't trust yourself, have a decent shop do the work.
