Welcome to the wonderful, oft confusing and frustrating world of reloading.
For new (newer) reloaders I suggest a copy of The ABCs of Reloading. While there are others out there, the ABCs shows how to, equipment used, component explanations, and even a bit about bullet casting. Your equipment is first rate, good quality equipment (I've always wanted Hollywood press!), and a others stated above, get a good reloading manual, clean up the tools and you'll be ready to start.
A couple hints; for starting with 9mm, find a load (tried and true "classic") in your manual before you buy components, and I suggest a 124-125 gr. jacketed bullet, with a "universal" powder. Begin with book starting loads and, if necessary, work up. I use the "plunk test" for all my semi-auto handloads and start with bullet manufacturer's recommended OAL for the bullet I choose (I shoot a bunch of RMR 124 gr. JHP which are identical to Nosler's bullets so I use Nosler bullet data).
Also, my
Rule #1, which I suggest to every reloader and especially new fellers is; I pay little attention (none) to any load data I see on any forum, from any range rat, gun counter clerk, good intentioned friend, pet loads website, or gun shop guru. I get 98% of my starting loads from published reloading manuals (forget the "one caliber" pamphlets as good reloading manuals have way more good info than just recipes), and just a few from powder manufacturer websites. I keep a log of every load (bullet, case, powder, powder charge [min and max], primer, OAL and crimp, and anything else that would refer to the load. In the "after shooting" notes I record best groups, shooting characteristics like recoil, muzzle blast, date shot, time of day and weather, etc.), and refer to that for subsequent loads, and I
always include maximum load data.
I started reloading in '69 (with a Lee Loader) and using common sense and my Rule #1, I have had only one squib (1970) and no Kabooms or near Kabooms...
Go slow, double check everything, and most important, have fun...
