First off, welcome to 3d Shoots! There is a lot of good info here and a lot of great people willing to help with whatever questions you might have.
Right now though it sounds like you really need to talk to someone face to face. I would start by doing a search for your local archery club. There will be a lot of friendly people there that would be more than happy to help get you started correctly. They will also be able to point you to the best Archery Shops in your area. Trust me this will get you pointed in the right direction a lot faster.
We will look forward to hearing how you progress.
