I would suggest in this order:
1. Watch several videos on YouTube to see what you are getting into, pay attention to different types of presses.
2. Get one reloading book, if you think you are going to use Lee equipment get the Lee Book, if not either Lee or ABC's
3. After the 1st 2 above if you think it is right for you get the second book.
4. Pick you equipment that you want to start with, watch a few more videos specific to that equipment. Note everything you will need so when you order you don't miss anything.
5. Take your time, make a few rounds at first, test them, then have fun. Never get complacent in the process, be safe.
6. If you have any questions at all, no matter how stupid they may seem, ask here or somewhere else, but definitely ask.
If you have the opportunity to learn from someone already reloading take advantage of that early in the process, to me nothing beat hands on experience.
