I'm fairly new to archery so I can comment only from limited experience:
1. I didn' use the spine chart to select the arrows. My only guide was
to choose arrows with a spine equal to or 5 pounds more than
the bow weight; I shoot a 55# recurve and I use 60# arrows with a
total weight of 425 grains.
2. I started with wood arrows but after I've tried the carbon ones I did
find that they are significantly more resilient when they hit
branches, logs, etc. that kept breaking my wood arrows. The only
thing that distroyed carbon arrows is hitting metal head on.
