Also, you may have read that clear Douglas Fir was (and still is) the wood of choice for stringers. 2x pine will certainly not give you the strength that Doug Fir will.
With that said, others make stringers out of foam and wrap them in fiberglass. You've got to assume that wood wrapped in fiberglass is stronger than that...
My suggestion is that you take a look at the other stringer threads here and on the other boat forums as well. Read the threads, look at pics, and post your own pics here.
It is a time consuming, frustrating, but very rewarding process.
AFAIK, the treated lumber is a worry if it's wet/fresh. It sounds like OP has probably dried his out enough to not need to worry about it.
I used laminated marine plywood for my stringers but that was just dumb luck instead of some kind of divine plan.
