The article looked more than capable in describing how everything should be setup. The article you pasted a link to even went so far as mentioning that you need to level shift the serial communications between the two devices, and provided an easy to read diagram of how he/she did so.
As far as being "newb to electronics", I can not help you with that, and you need to spend some time learning the various aspects you need for this project. Aside from that I really can not offer much other advice. Anyhow a logic analyzer would be your cheapest bet for checking the comms, but you could even get away without one *if* you can eventually get it working.
