Like Kenneth said above, we'll need to know your draw length, and ideally the center cut of your bow, to get you to the right spine. It'll be very easy to figure out the wood shafts when we get those specs, but for starters I'm pretty sure you'll be fine with either 45/50's or 50/55's, if your draw is near 28". Glad to be more specific when we hear more.
Those .500 carbons with a 125 grn point will be way too stiff; again as Kenneth says, you'll neeed a .600 for carbons, but it gets more complicated as far as length, point weight, total arrow weight, etc.
(Which is largely why I went back to just shooting wood after a season trying carbons).
