Arrow Help

New to archery and looking to buy my first set of arrows and just need some clarification since there seems to be so many factors.

I will be using a 25lb recurve bow, and my draw is about 28". I'm wondering what exactly I should be looking for regarding arrow length, spine stiffness, and the grain.

What I have come up with so far are carbon arrows that are 30" in length, 800 spine, with 100 grain points. Does this seem suitable or should I switch some of this up?

Thanks for any help.
