Another thing I see under select the correct arrowis a matrix that calculates the "adjusted bow draw weight" and that doeshave a recurve option.Would it be appropriate to use this adjusted weight with their chart?
While I'm at it I might as well ask another question. I was following the arrow weight post and am curious, if my shaft are 29" with all componants they come in at 475gr. (approx. 10.29 per/in) and 30" will add 11gr. to the total, will they do the trick for whitetail?
Thank goodness for easy questions.

Yes and Yes.
Don't just go by the spine charts though. Just as oftener as they get it right, they get it wrong. The correct spined arrow for you is the one that flies best and most consistent from your bow. Period. Spine depends almost as much on how clean and consistent your release is as it does on anything else.
