Since I am not going to be able to heat up the j-head how do I read the thermistor to be sure it is being read correctly by the firmware?Quote

Grab the RAMPS download from [www.makerfarm.com] (the might be embedded in the build document for the I3 there).
Then if you hook up your motors you can test.
Unless you disable Min-temp in the firmware you will not be able to test the heating functions without a thermistor. I would go
ahead and wire up the thermistor from your J-head and you can then test that it is being read correctly by the firmware.
Then with it hooked up you can test voltage on the hotend and heated bed with a volt meter.
The docs on Makerfarm also have a really good RAMPS wiring diagram.
