Have had nearly the same problems as you, but most of them could be solved .
ad 1) + 2) - I am using one port (that one labeled COM) for both uploading and monitoring

The other port is needed when you want to debug and yes you can (or must 
) connect both, but (at least under linux) you should be aware to connect them in the order COM and then USB - otherwise the device names would be reversed.
ad 3) To use the on board LED, I had first to solder a little bit as mentioned here and had to add lib Adafruit NeoPixel, but then …
