It would be best that before you attempt to "bust out" the porcelain that you try to get the piston in that cylinder to Top Dead Center (TDC), with both the intake and exhaust valves closed. This would lessen the exposure of the cylinder and valves to any debris.
We normally find TDC by feeling the air rushing out of the spark plug hole on the compression stroke when the engine is being turned over. When the air stops blowing out of the spark plug hole the piston is at the top of it's travel. But with your broken plug installed I'm not sure how you can do that. You could remove the valve cover and watch the rockers for that cylinder, but that's even more work that you don't need.
Any suggestions, anyone?
When you do get that damn thing out, make sure that you get all of the debris out of the cylinder as possible!
Good luck!

He said the reason it happened(don't know how accurate it is but he is a pretty good mechanic) was from changing the plugs while the motor was cold. He said the plug expands when it is cold and contracts when it is hot. He also told me there was probablly oxidization built up in the plug from the aluminum contacting the steel.

Changing plugs on a cold engine wolnt do anything.... by the looks of the plug, it looks like it rusted in there, and you turned the plug too hard, and it snapped off.
are the plugs stock? if they wernt, it could have been tightened down too much
