I too hunt with a bow, although I am not as sucessful with it as Kirby, I still have fun. I really enjoy 3D competition which also helps with the whole hunting thing.
Personally I'd stick with a compound bow. Pull as much weight as you can comfortably shoot. If you can handle 60-70 lbs then go for it, most Provinces have a minimum draw weight and in B.C. its 40 lbs for deer. As far as distances it all depends on how much you practice and what your comfortable with and the size of the animal.
The bow is just a fraction of the whole package the slightest little thing can throw you or your bow off so I can't stress the "Practice" part of bow hunting, you have to prove to yourself that your confident in your archery abilities. The last thing you want to be doing is tracking a poorly shot animal for miles and miles. Guessing yardage is perhaps one of the most important things with bow hunting, the margin for error between a good kill shot and missing the target completely isn't that much.
Like Kirby said we need more info on you, especially your arm span from the tip of your middle finger on each hand. And how strong you are?
