For reasonably priced arrows, Gold Tip XT Hunters are hard to beat. To me they just seem tougher than other arrows. But since I like to check out other options I picked up a dozen Easton 6.5s last fall to try out when I ran into a real good deal on them. I like them fine but I don't think they're quite as tough as the Gold Tips. I also got some Black Eagle Outlaws a couple yrs ago that I'm happy with. When my gf wanted to get into shooting a bow I grabbed her some Bass Pro Blackout Envy's (gold tips) on a good sale. They seem great.
For a saw, I mounted a Dremel on one end of a 2ft 2x64 with a screw in the middle and one towards the far end as 'guides' to roll the arrows against, doing my best to get it straight and square. It works like a champ.
