Welcome to the addiction, Battman. There are several sponsors here, myself incl, that should have everything you'll need along with plenty of advice and opinions. 5" fletch and Bohning Classic nocks is a good place to start. If your fletching clamp is helical, buy your feathers to match the clamp, left or right wing. If the clamp is straight, you can go with either wing, altho most fletch opposite of their shooting side. Minwax stains and oil base polyurethane make a great finish and Duco glue works very well with it.
Feel free to call and I can walk you thru the process. There are also some good instructions here in the how to forums and on youtube. Rick
