Great advice above and a trully methodical posting CD.
Hunting takes alot of practice and skill so don't become frustrated if you don't get the hang of it immediately. On the other hand you may be one of those folks that walks into the woods, sits down and takes home a wallhanger.
For actual hunting techniques and understanding whitetails I would also suggest heading to barnes and noble and picking up one of the whitetail hunting books. It should be able to answer alot of your questions.
