I've only got one judo point, and the rest are those little star shaped thingies that go behind a field point.......I think they call them turkey spurs or something like that? They are relatively cheap and won't let the arrow bury up in the grass like a regular field point will.
I killed a squirrel with one this fall and it was dead right there.
As far as shafts go, here's my favorite for on the cheap.
Go to your local hardware store, craft store, or even Wally world and get some hardwood dowel rods. They actually don't even have to be hardwood for that matter.....I made some out of pine. I sort through the whole box of 5/16 dowels and roll them on the floor to check for straightness. Sort out the straighter ones and put the rest back. Now look for any bad defects on the straightest ones and put those back. Now you have about a half dozen of the best ones in the box. I paid .57 cents a piece for mine at Wally world and with a tip and fletching, little bit of polyurethane finish....I'm out less than $2 bucks per arrow. Use bright fletchings.
Of course, I also put an arrow wrap on mine for visibility reasons and use bright orange feathers that I cut from full length stock to end up with 4.750" shields.
Just build them like you would any normal wood shaft and pay attention to the grain as much as possible. I didn't need to do any spining down of the shaft for my #48 Bear Grizzly they were right in the ballpark already, and they fly quite well believe it or not.
