You didn't specify what kind of projects you plan to manage. There are plenty of IT people around here (including myself) so I assume you mean IT project management.
1. Take small steps
People usually learn in special manner. At first they need small, easy, little successfull steps. So don't take everything at once. You will probably need to make many shortcuts, put some things in black boxes and simplify others. Decide what to learn at once and where to dig deeper. Use links above wisely :)
2. Know the reasons (or ask "why")
The project management is not about the practices, it's about decisions and reasons of those. I find it important to know what decisions other managers made and where it lead them. So I consider blogs as interesting (or even more) than literature. Maybe you should find people (other PM) you value and trust and track their blog entries. My personal top 3:
3. Take some practice
You wont get far with theory only. Not all the lessons one can learn from other's mistakes, so finding a company which will trust you and THE team is the first step in making your own mistakes. Try it sooner than later even if it mean very tiny little project.
