Matt,
I think the first thing to consider is what method of shooting do you want to do. If you are a gap shooter, the rest will not be a disadvantage. If however you want to shoot instinctive, the lower the arrow is to your bow hand, the better your pointing ability.
You can tune a bow off the shelf to shoot as well as one you use a button, and elevated rest. I have shot stickbows in each configuration, when done correctly, you can get flight that is better than our ability to shoot it consistantly.
For hunting, keep it as simple as possible. If you want an elevated rest, I would attempt to keep the button thing out of it. Having shot those in the past, they get dirt in them, they freeze up in cold weather, and you can lose the caps. My basic rule is simple, if it can break, and I can do without it, I do without it.
John gave you some good advice, you will likely get "Information overload". Just remember, in traditional bowhunting, there are more than one way to skin the cat. The joy, and the thrill is in finding your path. We are honored to be your guides, but you choose the path.
