With your height and draw length, I would opt for a longer ATA but that's just me. It will be more stable for you along with a string angle that doesn't resemble a >.
I'd also look for something with a brace height of 7 1/2" or more.
The longer ATA bows with the larger brace heights should make for a much more enjoyable shooting experience for a beginner.
Do you know any archers locally that you trust? They would be your best bet to help you get started.
Good luck, archery is very addicting.
