Avoiding information overload and how to begin learning about entrepreneurship from one source?

I am looking to get into starting my business (my first) and have no idea where to begin. Is there an online class or resource that provides most of the principles and concepts I should learn and know about?

I'm an entrepreneur as well, and these are the books that helped me:

The Lean Startup by Eric Reis - http://www.amazon.com/The-Lean-Startup-Entrepreneurs-Continuous/dp/0307887898/ref=sr_1_1?ie=UTF8&qid=1404414599&sr=8-1&keywords=lean+startup

Innovation and Entrepreneurship by Peter Drucker - http://www.amazon.com/gp/product/0060851139/ref=wms_ohs_product?ie=UTF8&psc=1

The Startup Owner's Manual by Steve Blank - http://www.amazon.com/Startup-Owners-Manual-Step---Step/dp/0984999302/ref=sr_1_1?s=books&ie=UTF8&qid=1404414809&sr=1-1&keywords=startup+owners+manual

Competitive Strategy by Michael Porter - http://www.amazon.com/Competitive-Strategy-Techniques-Industries-Competitors/dp/0684841487/ref=sr_1_1?ie=UTF8&qid=1404415123&sr=8-1&keywords=competitive+strategy

The main thing to keep in mind is to do as much as you can with the least amount of resources—keep lean. Also, validate your idea as soon as you can— you should make sure that you're actually solving a problem that exists. And TALK TO CUSTOMERS.

Read the lean startup. It should help you get on the right path.
