Wheels,weight is pretty subjective but a lot of people like about 10 grs of arrow weight per lb of bow pull weight.You could use that as a starting point,about 470 grs give or take.
Aluminums,like about any shaft can be any weight you want it depending on the shaft and head weight you choose.
I have been using Gold Tips for several years and "footed",they are extremely durable.I have yet to break one and I have treated them badly.
You can use a .500 spine arrow if you choose an appropriately heavy point.If you are dead set on one exact point weight,things get a little more complicated.
