As for question number 4 you can probably get a cheap tablet like the ones mentioned here: 49$ tablet works | DJI Phantom Forum
Enjoy, I'm a new owner of a DJI P3S like you and we got a lot to learn!

I had a tipover and capsized the drone on my first flight while landing and I will also only catch by hand! My props are a bit damaged on the edges and a bit more on the bolts.
Where did you buy it? I'm considering to buy one, but so far I only found it on Aliexpress (with rather high shipping costs of 110$ to Italy) while it is not available for shipping on Amazon.
