David,
You are going to need to shoot thru a chrono to get the arrow speed. As tall as you are you might have someone measure your drawlength also. I'm guessing you are longer then 28" and therefore are drawing more then 50#s.
Actually all the numbers mean squat, just shoot the bow and get good with it. If your arrow flight is straight and true, try some broadheads. If they fly the same. Your good to go.
Dang as good as the hunting is up there, I would be figuring how to get a spring bear hunt real soon.
