Hi - new to photography thus new to my newly purchased E-M5. 1. Love it even though I have no idea how to take advantage of 99.9% of its capabilities; 2. Whats up with the continuous "whirring"/fan-like noise emanating from the camera? Assuming its a cooling fan of some sort? Normal for it to be 'on' constantly?; 3. Thoughts on the best resource(s) for me to use to learn basics of photography so I can optimize my experiemce with this amazing camera?; 4 and lastly...if chronicling the lives of my 5 and 6 year old kids lives going forward from here (sport related activities, ballet, portraits, shots around the house/playground, vacation memories, etc) is the mission of the camera, what two additional lenses would you recommend I have in my bag (I already have the 12-50 Zuiko lens that came with the camera) to, once again, optimize the OM-D's capabilities as I continue to learn and use the camera?
Clearly a lot o questions and perhaps I have busted a forum rule or something with the long series of questions, so sorry and maybe hit just ome or two of the questions?

Thanks very much, TPBOMD
