Sorry about the delay.  I was going to design it all in Fritzing and post the Fritzing file, but not all the parts are available and I haven't figured out how to create the fritzing parts yet. So here is just a photo. The blue board is the one from Adafruit and is the charger, the smaller Sparkfun is the fuel gauge and the square Sparkfun is the StepUp 5V.  You can grab the actual pin outs from the Sparkfun and Adafruit site but the connection is shown below.  If you decide to use the fuel gauge let me know and I can post up a class polling the fuel gauge.
 

Hi Dave,

Thanks a lot for that layout.

But do you mind sharing the fritzing part files for the lipo fuel gauge please, could not find it in the library.

Much appreciated,
