Blinkfeed can't be turned off. I've researched and tried lol. The best solution is to change which panel (or screen) is your home screen and move the Blinkfeed screen far left (or right). All I can answer on the photos is our camera are 4mp,but I've only had this phone for a couple days and I am impressed with this camera. Hopefully someone else who is more camera savvy can answer your question.
