I don't know how much boost it is making, my buddy said it is a large turbo and it is about as fast as his Solstice. I am running premium. I could try stock and see if I get any ping.
I doubt you'll have a problem at all with the stock plugs. Going with premium fuel should have afforded you all the protection against spark knock from plugs that you will need unless you're running high boost (in excess of 10 psi on the 2.8) which in this case I doubt because I suspect you do not have a boost gauge which you need to get right away. If there is any intercooling or alcohol injection, that will also work in your favor. Stock 2.8L compression is relatively low compared to what factory turbo cars are running now although with aluminum heads.
