nomad_archer,

Get a copy of the Lyman Shotshell Reloading Manual and read it from front to back - There is a world of information that you will find useful to get started, and much that will be helpful down the road.
It will tell you about useful loads and direct you to the proper components to use and match together.
There used to be adds in the book for some sources as well.

Good Luck,
Ted smile
