Welcome to the gang!
Before you get too concerned with hunting deer, be sure that your 36#'s is legal to hunt with. A lot of states have a 40 or 45# minimum requirement.
To optimize penetration with your draw weight, I would shoot as small a diameter shaft as possible. Also, as heavy of an arrow that you can shoot consistently. I would also use a broadhead with a high mechanical advantage, like a 3:1 ratio. At 36#'s, keep the shots close, like 15yards or less, and avoid awkward angles and large bones.
Good luck, and let us know what you come with.
