First and foremost start reading. Before you invest a dime in equipment, spend some on reloading books - just a couple to start.
You'll need quite a bit of equipment for this cartridge since it's a necked down cartridge. Case trimming will be an important step with such a round. Think clean, resize/deprime, trim, prime, charge, seat, crimp. Those are the steps, but there's a lot of fine tuning involved in some of them.
Get hard numbers and then throw them at the group and ask opinions. Reloading is more of an endeavor than shooting. In short, your question is simple enough to be equated to "how do I lead a successful life?". You should explore a bit more and narrow it down.
