Thanks so much for the guide.
TP28 can be used for the reset. TP28 is on the opposite side of the board and is near pin 1 of the usb connector and also near C7. This is a much larger pad and easy to solder to. I successfully programmed used TP28. If you solder a wire, keep it short it might be sensitive to noise pickup.
I also used the 6.84 SDK which can be found here, look under z-wave-500-series.

For the PC controller software, that does not seem to be available as a direct link. One has to download simplicity studio 5, from within the application it gives you the option to download other software including the controller.
