Hello, I'm Birdy.
Not sure what much more you want to know. There is the same 6 pin header that's present as on the other revisions. It looks like they've moved it from the front of the processor (LED area) to the left side (power led side) of the board. JTAG is usually a 5 pin configuration, so I'm not sure of it's function. Those headers are usually placed very close to the processor or pld or fpga, so it seems strange that it was moved so far. But as far as your list goes...
