Well first off, WELCOME to the ranks of bowhunting! It is definately a journey and not a destination, but it will make you a much better hunter overall as your knowledge of deer and their behavior will by necessity increase significantly.
To address your questions, I will break it down into two parts, your equipment and then YOU.
At this point as far as the equipment goes all you can do is as the other posters here have mentioned and make sure that you bow is tuned right and matched to the arrows. I wouldn't really worry about a whole lot more than that right now.
Now to you.........
The bow you shoot is only going to be as good as you are. What you need to do is preferably have someone who knows about archery teach you the basics. Shooting a bow revolves around 5 things......the DRAW, the ANCHOR, the AIM, the RELEASE, and the FOLLOW THROUGH. This is called the SHOT SEQUENCE and is the exact same in importance regardless of what kind of bow you shoot, compound, recurve, or even a stick you find in the woods and make a bow out of.
These 5 things must be performed correctly and CONSISTANTLY and without you consciously having to think about them. That's what's called ingraining them into your muscle memory. It's like shooting a basketball, playing an instrument or riding a bike. Once you are rock solid in your form and can perform the shot sequence automatically THEN you can start worrying about your accuracy because until you have it down you will have no accuracy.
This takes the shooting (correctly I may add) of literally THOUSANDS of arrows and is not something that you achieve in a few weeks or even months. What you need to do is to not worry about shooting at any distance, but practice up close. When your arrows start grouping (even if the group is not where you're aiming exactly) THEN you know that your form is beginning to solidify. Once you are consistantly grouping arrows then you can tweak your sights and other gagets you may have on your bow to move the group where you want it.
I started out on recurves and then shot compounds for 26 years before going back to the recurves and believe me it's ALL archery and the basics are the exact same.
PLEASE feel free to ask any questions. We are more than willing to help you get started.
One final thought..........I wouldn't plan on shooting at any live animals this season. You have a long way to go my friend, and once you do become consistant then we need to talk about SHOT PLACEMENT with an arrow. If you've only gun hunted that is a very important part of bowhunting that's somewhat different than hunting with a firearm.
Best of luck to you and HAVE FUN!
