Point weight will affect arrow spine, and that shaft and point weight should give you a reasonable starting point. Get screw in points so you can play if necessary. A stiff spine will shoot left for a right hand shooter and a weak spine will shoot right. Another consideration with point weight is the arrows F.O.C.; which basically is how far forward from the center of the arrow the balance point is. Depending on what you are using the bow for there are some recommendations. General target shooting is 8-12% with the heavier end being more important if you are going to be shooting long distances. Hunting is 10-15% with some wanting 20-30% if they are hunting really large animals. Google Dr. Ashby and wade through that if the subject interests you. Target shooters will generally shoot for an arrow weight of 8-10gr per lb. of draw weight while hunters generally fall into the 10-15gr/lb. I am running Easton Legacy's with a total weight of 486gr and I'm drawing about 46.5# thus giving me an arrow about 10.5gr/lb and a FOC of 14.4% with the 150gr heads I'm running. I'm using 5" feathers as I need to stabilize broadheads - a target archer can get away with shorter ones. Wood, aluminum or carbon - mostly personal preference; people use wood mostly just to be traditional but they are likely a bit more fragile than aluminum and carbon is certainly tougher than either - you're making the right choice by going that direction, I went aluminum just for the extra weight and nostalgia. (that's what a shot out of my recurve as a teen). That's probably more than you wanted to know but there you go!
