RE: Shooting range
Bones, you're fine where you are.
My hunting bow is set at only 50#, and it flings my arrows at only about 210fps.
At 20 yards my arrows, tipped with 100 grain Thunderheads, will blow clean through both lungs and 2 ribs, and then bury themselves in the ground on the far side. It will also, at the same distance, drive one of those broadheads into a deer's vertebrae deep enough so that you can't see any blades. Yeah, I screwed up the shot and hit high, but he dropped on the spot, and provided an easy follow up. It was good to know just how hard they hit.
I started at 60# because I wanted more energy, but found that after freezing my tail off that I couldn't pull it smoothly enough to keep from being noticed. It's also a lot tougher, and maybe impossible to fraw from an akward position, which hunting will demand of you from time to time.
Adding draw weight will flatten trajectory which will take some guesswork out of range estimation, and it will raise the kinetic energy that your arrow delivers, but your setup will be fine just as it is.
