RE: Getting started
You need to get a bow that fits you--if you draw 30", don't get a 56" bow. Keep in mind that for every inch you pull under or over 28", the poundage will increase or decrease. You can generally get a good recurve cheaper than a good longbow. Martin probably makes the best "over the counter" bows on the market, but in my experience they start stacking if you draw much past 28". I haven't shot a PSE in a few years, but was not impressed with the quality of the ones I have shot.
Starting out, you may need a bow that is lighter than you want for hunting. You need to establish your form and accuracy first--this is usually much easier with a lighter bow. I figure 30-40# is what most men can comfortably shoot and control, at least starting out.
You will need arrows, a glove or tab, a target, and a bracer (armguard). A good book and/or video to help you with the basics won't hurt either--I like Byron Ferguson's "Become the Arrow" (book) and Ricky Welch's Instinctive Archery Vol. II (video). Don't try to follow their every move, just get the basics then use what works best for you.
As far as the arrows go, you can get some close guesses but the final tuning will be up to you. I like to stay with 8 grains per lb of draw weight or more. I wouldn't start out with wood arrows--they have their own particulars to learn, and you need to get your shooting down without having to wonder if it's you or your arrows. I love wood arrows, and shoot them myself, but they take a little more understanding than aluminum or carbon.
Good luck!
