sounds like you are on the right track.
I agree not to get over bowed...but to an extent.
I personally think 99% of average men could very easily shoot a 50-55# bow and not worry about developing bad form etc anymore than with a lighter bow. But that is just my opinion.
A 45# bow at your 30" draw will be deadly on all but the toughest game and definitely deadly on Black bear as well as deer, hogs, elk, etc! your long draw is a big advantage. A 45#er at your draw would be like a 50-55 pounder at my 26" draw because of the longer power stroke you have. Think 150# crossbow VS 70# compound bow. Very similar because of the different power stroke.
so keep in mind you are at a major advantage.
TJ's book is about the best I have read on getting started and covering all topics. I would suggest getting that book right away.
to get started you will need a bow, arrows, glove or tab, armguard, arrow points, STRINGER for the bow if it doesn't come with one, and you are good to go! I would also suggest a couple judo points in the same weight you get your practice tips/broadheads in so that you can stump shoot, rove and shoot at anything.
With your arrows you will eventually need to bare tune the shafts to get them perfect. so id suggest having 3 rivers or where ever you buy your arrows give you a good recommendation for a good arrow for you. then just buy 6 of them. The reason for this is that to properly tune an arrow you need to have your form situated. you don't have that yet so just get a few arrows to start shooting. then in a couple months you can start tuning shafts and finding what will be best for you. That will also give you time to figure out what type, weight, etc arrow you want. Short version....don't go to crazy spending money on arrows yet as they will most likely change when you figure everything out and get your groove.
You are going to have a lot of fun with this. There is nothing like Traditional bowhunting.
Welcome aboard and enjoy the ride.
