Practice shooting whatever bow you decide on as much as possible. Can that "ten fingers of doom" bow be adjusted to higher weights? I would recommend getting the weight higher. If it is as high as you can comfortably pull then practice will strengthen the necessary muscles and allow you to gradually increase the draw weight. The higher the poundage the flatter the trajectory.
Beyond the bow itself, you can look into the things that attach to the bow. Good sight. Stabilizer. A quiet quiver. Arrow rest. Will you shoot with your fingers or a release? Will you use an arm guard?
All the other stuff is secondary to getting your bow set up the way you will hunt with it and getting out as often as possible to practice shoot. Getting familiar with the bow and the sight pins is huge.
