Hi Hung,
I don’t have experience in the MSP430, but I suggest you to get a development board of the same IC and get started with it. The development board comes in small sizes convinient for any kind of projects. You will get a lot of help from the CD along with it if there comes one along with it, or you will surely get help from the TI website.
Regarding the RF module, are you going to use zigbee module? The zigbee module is very fast but the range won’t be enough for your purpose.
There are lot of RF modules avilable which can have range more than 200 meters.
