Welcome aboard, Blake, and welcome to the hobby.
MacBaren has some good info available on their Expert Knowledge page. Sometimes the wording is a little odd, because English is not the first language for these folks, but it's not bad.
Other than that, I would give the following advice:
There are no rules in pipe smoking, but there are what we might refer to as "best practices" - lessons learned from long experience. Ask questions - there are some folks here with lots of experience.
Buy the best pipes and tobacco you can afford. This does not mean you need $400 pipes, or can't smoke what one might refer to as the "American Classics" - Carter Hall, Prince Albert, and so on. But I am convinced, from my 40 years experience in pipe smoking, you will get more enjoyment from having 1 good quality pipe that cost you $75 - new or estate - than 3 cheapies at $25 a pop. (Good quality corncobs are an exception.) And the really low-end tobacco - the kind that is really cigarette RYO tobacco relabeled to avoid taxes, or sold in drugstores for $20 for a 12 oz bag - is best left to the RYO folks.
Other than that - take your time. Explore. Relax and enjoy. I know it's easy to be impatient with a new hobby, because one is full of enthusiasm. But pipe smoking is best when it is savored - and that's the best way to approach the hobby, too.
Thought in the early morning, solace in time of woes,
Peace in the hush of the twilight, balm ere my eyelids close
