Removing the rotors from the hubs can be quite a challenge. I use an air chisel. My thought on rotor resurfacing is this...if you are going to go to all the trouble to remove the rotors from the hubs, don't resurface them, just replace them. On the other hand, if you aren't getting any weird pedal vibes and if your brakes are working fine, just replace the pads and leave the rotors like they are.
Bearings are a judgement call. You will need to thoroughly clean each one in kerosene or equivalent and meticulously inspect them for wear. If they are damn near perfect, re-pack them and move on. If not, replace them.
