How do I load the Demo temperature program on an MSP 430 access point and end point?
This is more an extended comment than an answer...

Well the first step is to download the code, extract it somewhere and in CCS use option Project->Import existing CCS Eclipse Project. 

Then browse to the directory where you extracted the project. Go to subdirectory eZ430-RF2500 Wireless Sensor Monitor\Embedded\CCS\eZ430-RF2500_WSM and select it.

CCS should detect project now. Check the automatically import referenced projects box. After that, you should be able to build the project. Connect the board to the computer and click debug. If everything is connected correctly, CCS should load the code onto the board.

You should also take time to read the readme files in the project directory and the comments in the code.

I don't have that board, so I can't check if that's all that should be done. It may be worth taking time to resolve the warnings that appear after building.
