RE: Just getting started
My best advice would be to find a fellow deerhunter in your area or someone you will be hunting with, ask them a lot of questions, and offer to help them with putting up stands, clearing lanes, finding good spots to hunt (scouting), planting food plots, etc. Getting your hands dirty will probably help more than book knowledge. But as Zubba said, reading up a little bit on some tactics and common knowledge could be helpful.
Lastly, get a good rifle and scope and practice with them until you are a constitently good shot.
