Answer 1

I think you can't just flash your arduino via iPad untill there is some kind of arduino IDE for ios if you mean this.
At least you can make a script for your arduino board to listen serial/usb port for commands (may be there is some usb-library for this purpose), then make an ios app to send commands via usb/lightning port. Connect your arduino board to the iPad using some adapter so that you will be able to control LEDs depending on your script.
All in all it is better to use ESP board to avoid all wire stuff and just use wi-fi connection. Also Arduino IDE supports ESP boards. But you have to make script for arduino board and make an app for iPad anyway.
