Welcome aboard. I would also recommend lower poundage bows. I would try to stay around 45 pounds or less AT YOUR DRAW LENGTH. If you can find a traditional shop in your area or a friend with a traditional bow, have your draw measured. An AMO 45# @ 28" bow drawn to 29 or 30 inches is 48 to 51 pounds. That weight is not outrageous, but lighter is better for learning. You will also need to make sure your arrows are matched to the bow. Poorly tuned arrows make learning difficult as well.
Start with a good used bow, and if you are like most of us here, you will soon have a collection.
