Regarding getting your crimps correct:
I have not mentioned this before, but I think it is useful to make up some dummy rounds whenever setting up for reloading a new cartridge. This is especially helpful in getting the crimp correct.
I understand you were probably focused on making some live rounds to try out, but it really helps to sacrifice a few cases and bullets to make up some dummy rounds without primers or powder in them.
I suggest when you get your loading press you do so. I always do this when setting up to load a new cartridge for the first time. I can sacrifice a bullet and case or two getting the crimp correct and not worry about wasting powder or primers while setting up my dies. When you start loading a new cartridge you always have to set up your dies. This is nothing more than adjusting how deeply you screw the dies into the press. Most dies come with a locking ring, and when you have set the die where you want it you snug down the ring against the body of the press, then lock the ring in place on the die with a set screw. So the first time you load up a particular cartridge, you need to set all the dies. My advice is, do not be in a hurry to start cranking out live ammo, first take the time to set your dies correctly, and the way to do that is to make up some dummy rounds.
Particularly with the seating/crimping die, the setting will be specific for any particular bullet style. If you change bullets, you will have to reset the seating/crimp die for the new bullet style. Having a few dummies on hand is always helpful to reset the seating/crimp die back again to where it was for a dummy loaded with a particular bullet.
Here is a shot of my RCBS 45 Colt dies that I have been using for many years. I always like to store a few dummy rounds in the box with my dies so I can reset my dies if necessary. There is an extra seating/crimp die for a different bullet, and all the dies are wearing their Hornady Lock and Load AP collets.
Don't worry about how to set up your dies, any good set comes with instructions for how to set them up. If you can't figure it out from the instructions (which can sometimes be a little bit unclear) there are plenty of folks here who can explain it to you.
