Cooking the rocks will not kill of everything it is just a good way to get rid of built up nutrients, PO4, algea etc. from them. They will still keep all of their "live" bacteria and stuff.
I do agree on the cycle though - I think you will have one. The other thing to think about is that you will no longer have the biological filtration of you live rock in your system so it will be a lot harder for it to process the same amount of detrius (sp) and you may have problems with ammonia, nitrate and nitrite without it.
