Welcome to the club! I have been reloading for over 30 years now and all i can say is that there is something new to always be learned! I highly recommend the Lyman reloading manual being it is chock full of info on the theory and practice of reloading. They have seemed to write thw book when there was no others. It is good to have 3 or 4 different manuals being you will find some variances in the loads due to firearms used and some will cover powders that others will not. Take your time and if possible link up with a reputable handloader who knows his stuff. Ask lots of questions!
There are advantages and disadvantages to both kinds of dies. You have to look at what you are doing with them.
