318--You are Doing It Right, planning to ask lots of questions. Guys on TFL will answer them, too.
Might I suggest a textbook of reloading to study: The ABC's of Reloading
published by Krause www.krause.com
You can find it @ yr LGS, gun sho, order it over the I'net, or from the publisher.
Covers beginning and advanced reloading, good explanations, clear illustrations. A VERY handy reference. Should be on every reloader's bookshelf, well thumbed, IMHO.
