I need to get a piece of sheetmetal to screw up into the frame of a broken damper so I can seal off my chimney for a set of unvented gas logs. Any idea on what thickness or grade of sheetmetal to use for a high heat area such as this? Also, the damper is some pretty hefty steel..any ideas on how to drive a screw through it..a special drill bit maybe?

Use a thick piece (at least 1/2", probably 3/4") of cast iron or high-carbon steel. You probably would want a drill press to drill through something that thick, then use the biggest self-tapping screws you can find. You might also want to cap the top of the chimney to keep birds and stuff out.

That hefty steel is probably wrought iron. Because of the complexitiy of a standard fireplace, there are several variables that need to be evaluated by an expert. You might need to get the chimney cleaned, or you very well might have to use brick or concrete block to seal it off.
