I'm not so sure on how much you can get a "user friendly" version of early church history. Frankly, such was anything but user friendly time and amazingly steeped in extremely controversial and complicated matters.
The best way to study early church history is to get your hands on primary documents e.g. the Ante-Nicene series, as well as a few general survey's of church history, which will cover the basic issues and such of the early church. THen if you want, get books on various topics/themes of the early church. But you will find most of these books are simply based on what is found in the Ante-Nicene Fathers.
For an a solid, brief, and more "friendly" survey of Church history, I'd strongly recommend "Christianity Through the Centuries" by Earle E. Cairns. He has more than enough chapters in his book on the early church to wet your whistle, and each chapter has a recommended bibliography for future reading. It's also a good survey for the rest of church history.
