No, and No! The GPS feature here embeds location info into the image data, and will also let you know about places in the area, but will not give you directions. The WiFi is used to transfer photos off of the camera and onto your smart phone, or your home computer.
No, not to my knowledge and I have gone through the manual and have not seen anything in it either. There is software that allows images from movies to be pulled though and that may suit what you're looking for. Here is a link to the manual for this camera. Nikon is good about making these available and it helped me in deciding to purchase this cameral. I hope this helps.
