  If you need to ask these questions, you aren't ready (nor do you need) to write a game engine.You can still, of course, use existing engines and are in fact encouraged to do so. In the realm of freely available engines, there are few good "game" engines, but most people glue together distinct rendering, physics and audio engines (et cetera) to build their own games.However, it's difficult to provide you much in the way of guidance with the level of generality your questions involve. You'll need to be more specific because choosing tools is very much about understanding your specific needs and determining if a tool (engine or library in this case) can meet them.
