My advice is to absolutely 100% get carbon arrows! They will survive the punishment you are going to put them through so much better than aluminum and will wind up costing you less in the long run by avoiding the bends, dents and creases you'll get in them.
You are going to shoot ALOT most likely and at close range so you'll be smacking the heck out of them, then when once you get outside you'll be missing and slapping the target and hitting trees and rocksetc.
I can guarantee you that I would go through aseveral dozen aluminum shafts for 1 doz of the Gold Tip Traditional shafts I've been shooting.
They are super tough and I haven't broken one yet on anything.

Also, as cool as those dull natural looking barred feather look........for now go with the brightest feathers you can find. (Tru flight makes a series called "Bright stripes") At this point you want the most obnoxious easy to see combo you can find.
Trust me you will try dumb out of range shots for fun, you'll stump shoot, and you WILL MISS. Nothing more frustrating than actually LOSING arrows.
Make them easy to see. Your priority with arrows right now is durability and findability.

Whatever you decide on, longbow or recurve.......figure in your head what weight you think you can handle or by pulling at a bowshop, and then drop that weight by 5#.
If you start out overbowed it is going to push your learning curve WAY back. You're going to use muscles you didn't know were there and if you can't anchor and shoot comfortably you might as well just throw the arrows at the target.
