I can remove everything but these. Im trying to install longer wheel studs and this is the only thing holding me up!!!! Also what is the little bolt that is on the front rotors that the wheel goes over? My spacer will not fit because of it?

 

The bolt you reference is to prevent the rear wheels from being placed on the front by dumb folks. It can and should be removed.

To remove the Rotor, obviously unbolt the calipers and support them, then yank off the rotor. They are not bolted or anything but may be rusted on a little. Bang them with a rubber mallet to free them.

 

350 said it. Hit em with a rubber mallet all the way around, that should loosen them up. Also, for the rear make sure the parking brake is off or they will not come off.
