I know this is rookie stuff but what is the best non platinum for high performance in the 968?

Mike, I don't know if this is what you're looking for, but I am running Bosch Super Plus 7900 WR 7 DC+ in my car. As close as I could tell, they are supposed to be the current stock replacement plug for our cars. They seem to work fine for me.

There's really no such thing as "high performance" spark plugs. Either they give you effective combustion or they don't (some combustion chamber shapes seem to not like some particular plugs). Besides using the correct heat range, the only choice is copper vs platinum vs iridium...the only tradeoff there being cost vs service life.
For the 968, which allows a full spark plug change in a few minutes, I don't see any reason to use anything other than the stock Bosch copper plugs.

Basically, yes. As plug wires age, they get brittle and crack. some of the spark will actually 'leak' out of the insulation. This can be seen in a very dark garage with the engine running. You will see a blue-white glow or spark along the wire where it gets near a ground point like the upper cover. When the wires are replaced, you should not see the spark light anymore in a dark garage.

Mike, what I am using is a single prong copper with yttrium, whatever the heck that is. Yttrium I mean.

Mike___ all Bosch Super Plug copper core w/Yttrium are single prong. Doug ___Yttrium is a chemical elementw/symbol Y atomic # 39.It has a melting point of 27773.4*F & a boiling point of 6038.6*F it is grey in color & was discover in 1794.

Ernie, it looks like yttrium can handle the heat, probably conducts electricity pretty well too, unless they use it as an insulator. I haven't looked into it.

There's something wrong with your numbers. an element should melt, long before it boils. Unless you're using non-standard pressures, which might lead to sublimation? At STP one of those numbers is wrong.
