Since you are completely new to cycling it might be beneficial to just get out and put some miles on your bike. I'd ride with your biking group and focus on having FUN! When you are at the point where you need that "something else" in your riding, then you can focus on actually "training."

If you want to race, I'd ride out the rest of the year getting comfortable with biking in all aspects. (I.E. Maintenance, changing tubes, cleaning/oiling chain etc...) Then you can train all winter and be ready to hit next year hard. I use Training Peaks for all my training needs. You can also higher a personal coach which will use Training Peaks to help you if you find yourself lost.
