In all honesty your situation sounds like one that could be easily remedied by a quick stop at a reputable local pro shop. They can size you up for draw weight and draw length plus determine if a right handed or left handed bow would be more beneficial to you and your specific requirements.
However, if that is not an option, Ebay can be a good place to find some good bow deals. Case in point, I have two bows up there now that I am auctioning off.
To help you with the draw length issue take a gander at this chart. It should get you relatively close to your proper draw length. Hope this helps somewhat.
How to Measure Your Draw Length
Draw Length can be determined by a measurement known as 'wingspan.' This is simply a measurement and has nothing to do with how you actually draw back your bow.
How to measure your wingspan:
1) Lean against a wall, standing as close to the wall as possible with back flat.
[/b] 2[/b])Extend your arms and fingers out as far as possible
3) Have someone make a pencil mark at the end of both your fingers tips
4)Measure this distance
This is your wingspan. Find this number in the chart below to find its matching Draw Length.(For example, a wingspan of 67" would be a draw length of 26") [/i]
