Yes, I know, covered in detail . . . what are the best performance orientated plugs for this engine? I am currently firing off NGK Iridiums, but have heard these are long-lasting, not conductive as other (copper?) plugs

IMO you shouldnt be looking for a hp increase with ur sparkplugs. As long as it delivers a reliable spark why bother chasing a 1hp increase?
Agreed. As long as the plugs are the correct heat range have the right gap and run the car they will be ok.
Stick with NGK brand or genuine denso. Probably BKR6EP-11 's. Drop the 11 off the end for a turbo or superchared version.
