Hi, DaCoda:
Welcome to Leatherworker.net. It sounds like you're off to a good start with your beginning tool kit. Tandy will be a good place to get your leather, too. Belt blanks are an easy way to start building belts, and double shoulders will give you good-quality leather to create wallet backs, etc. If you have the option, it's always best to shop for leather in person so you know what you're getting.
This site is a great place to ask questions and to search old threads for information. Virtually every topic has been touched upon at one time or another.
Good luck, and we look forward to seeing some of your projects posted here in the future!
