OK, here goes.
Odds are you wont be making arrows, but you may end up assembling them. Wood arrow are a bit easier, to me, than aluminum. not as many parts needed. You don't have to have inserts, just a nock cutter. You don't need a cut off wheel, just a knife, guessing you have one of those.
Actual feather fletches do after a awhile go bad, by drying out, or getting eaten by mites. I've got arrows I built 25 years ago that are fine, still usable, finish is good, fletches are good.
There's a lot of companies that sell shaft material, or if all your shooting is 45#, 5/16 ramen wood dowels from a hardware shop will work. A lot of places may get a bit pissed about you standing there going through a box of shafts for an hour or so to find all the straight ones, not just straight but grain running from one end to the other, tip to tip.
I'm not sure what your actual plans are for this bow, but if all you plan on doing is throwing it in a closet after you get it shootable, then its not really going to matter. Shooting in the traditional way isn't as hard as you think, but it is a perishable skill. doesn't take that long to get back into the swing of it as you would think. As long as you get your technique and skills down before you give it up or put it away in the closet.
Shooting a few times a month is enough to keep your basic skills up. Not going to be slinging arrows 50 yards and hitting anything but 10 to 15 is doable, and more than enough distance for hunting.
as far as how wood lasts when left outside, or getting wet in the grass. It depends on the finish, I've found arrows after a year in the woods that were trashed, but I have found a few that were in pretty good usable shape.
defthane spar varnish thinned out with paint thinner is what I use. Thin it out to about alcohol thin and dip them nock down and let them hang dry. I use 0000 steel wool in between dips and usually do 5/Five dips. Let them dry between dips, and dip them in and pull them out, don't let them stand in the finish.
Get a fletching jig and some plastic nocks, and a nock cutting tool, and a tube of duco cement and some ferril tight hot melt glue and your set.
BUT, if all you want is consistent shafts that you can just buy online, and all you want is shafts that will hang there in a quiver, then as much as I don't want to admit it, carbons the way to go.
If you're into archery, it doesn't feel like practice when you're shooting a couple times a week. Who knows, try it you may find that you're into it, and not just hang it in a closet.
Good luck.
