Changing Wheel Bearings, Rotors and Brakes

I have never done this type of repair on a car before, so am not sure if I need to do extra steps or not for this. I intend to pull off the wheel and then take off the disc brakes and the rotor to get to the wheel bearing. I understand they are sealed bearings so I will just be switching them out. I see from diagrams that I need to yank out the wheel bearing seal. Is they correct for this year of car? Do I need to get new seals? Can I just pull things off and then clean up what's there and then replace with new items or do I need to do extra stuff? Like I said I've never done this deep of repair, but the shop wants $700 to do it! I'm trying to do it myself. I ordered all parts from Rock Auto to save money and after the shop said that much money I decided to do it myself, but I'm leery of messing things up. Please help with step by step instructions. Thanks. P.S. I am a disabled veteran on a fixed income and need to save all I can. Thanks.
