Amateur question about devices integration

Hi everybody,
I have a really fast question, I don't have any background in hardware design, also I don't know how to assemble all the devices into a circuit board.
I have three small devices: nRF24AP1 chip; MSP430 MCU; MMA7341L. How can I integrate it into a power supply board that it can work together? Is it easy to do it or we need to have a special set of tools?
I want to design a device like in this project: http://bit.ly/eGjfrt
AFAIK, we have sensor and base station. The sensor have all 3 devices above on a board. The base station have 2 (except MMA7341L) on board. Is it right?
After we design the two of circuit board, is there any step we need to make it work? Does it require anything to connect the base to computer?

Since I don't have background in this field, these above question is naive, please help me understand it. Thank you very much!

You should consider building the prototype version on a breadboard.

Some links to give you a general idea.

To accomplish your task, you will need some basic electronics skills like using a voltmeter (or multimeter) to set voltage levels or you can easily damage your chips.

I know about using breadboard to design circuit. It's a simple process. But what I want to know is how to make it works? Like how to connect it to the computer to read data. I think we need to have some kind of device that we connect our circuit to there and after that we will read data through the device. Do we need any kind of driver, to make the circuit work?
I want to know the process of how to design a circuit (what component we need to make the circuit work) and how to connect it to computer, to load instruction to device to make it run, and display the information from it on the computer.
This is the hidden steps the above link does not state because it's too easy. I want to know the process only, not specific steps.
Thanks

For the computer connection to read data, looks like they connected the Mega644 chip to a Max233 chip. The Max233 chip creates the RS232 data interface for the computer.

Does that help you or perhaps get one of your questions answered?
