The beginner's section on this site and others cover these topics exhaustively. Scanning that section, and searching for specific topics, will turn up a wealth of info.
I'm intending this not as an admonition, but as helpful advice. There's a steep learning curve with lockpicking, and it's not uncommon early on to feel like you have no idea what's going on. Learn as much as you can about how a lock works, and practice as much as you can. Good luck!
