I dont know if the board comes with the resistors pre-installed, but they are 0603 SMD's, so not to difficult to solder on if not already there.
It appear the 2.2k resistor is for the Power On led going to pin 5.
I would be very careful not to short pin 7 (+3V3-C) to ground.

I'm pretty sure those are the 'onboard' LEDs, installed. DrFx says they're 'in middle of board'... can't see 'em when in enclosure... wants to install panel mount... when I've more time maybe... gettin' old, Dries...
I've attached two pictures in the links provided they are high resolution of the Blue Basic. Open the image if a separate tab and zoom in if you need to see more details.
