at your age and size almost any bow manufacturer has a bow that will fit you now and for as long as you want it. I would guess you have a draw length of about 26". Not sure how strong you are but I would look at a draw range of 35-50 lb. or if you can handle it, 45-60 lb.
For whitetails you can easily kill one with a 40 lb draw with proper arrow placement. But at that draw weight you better use a cut on contact broadhead like the Muzzy Phanthom or Magnus Stinger or Slick Trick's Razor Trick.
