I have made the first step in getting an entry into the TI msp430 design contest: getting the LED to blink. The msp430 development kit comes with a JTAG flash emulation tool, a small dev board with a 64 pin ZIF socket as well as IAR workbench kickstart software. Running the IAR workbench is pretty easy so I opened their LED blink example and was able to compile it and then put the device into debug mode to download the binary onto the device and provide a clock via JTAG. After doing this, I verified that everything worked fine by unplugging the JTAG tool, hooking up XIN, XOUT, DVcc, DVss and \RST to a breadboard and a benchtop powersupply. When I applied power, the LED started blinking and I could see it blinking all the way down to about 1.5V (below the 1.8V spec for this MSP430F149.) Throwing in the JTAG tool/IAR workbench manual at the bottom.
