Sorry, but PM is much more than "creating lists of tasks and getting them done." PM is about completing the project...
1. on time
2. on budget
3. to the specified level of quality
4. while constantly measuring the 3 items above
If you'll be managing more projects in the future, I would seriously look at a certification program based on PMI's PMBOK. The PMBOK is the project management bible. If this is a one-time thing, you can probably get by with one or two good books from Amazon.
Since the PMBOK assumes a waterfall methodology, you may need dig deeper into Agile Project Management if you're going to do iterative development.
