Jama gave me some great info on using a Rasberry PI to control all of this setup
Here is the detail
I just grabbed a one of these bad boys
http://www.auseparts.com.au/index.php?route=product/product&product_id=118Also the relay board u had was using arduino so i thought i needed one of these interface I/O boards

http://www.ebay.com.au/itm/390568255094?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649You dont need to get the $120 version of the PI or the Seperate ARDUINO I/O board but i did because I am a nerd ...lol
Here are some links and advice
That looks like a good Haul of stuff.
The IO board is not necessary but it is better to have it (I don't)
As the Pi's pins are only 3.3v logic where that relay board uses 5.0v so that way is better for the pi
You are on your own getting that working i'm afraid.
What I can help you with is:
Getting your pi accessible through the internet.
Read these 2 tutorials to get a dynamic address that auto updates.

http://www.youtube.com/watch?v=wGahWkjettwI will draw you a diagram on how to connect the relays and get that over to you tomorrow.
A warning in advance, you will be splicing the mains wire 110 or 240v so know what you are doing and take appropriate precautions. Also it does not comply with any safety regs.
And also
I have had a quick look into that board and it appears you can use it just as an IO buffer, which is what you want.
Meaning that if you connect it all up. when you toggle port 1 for example on the pi, one port should go high on the board.
I have drawn a very rough diagram for 4 channels.
The numbers I have used are just for example, and I have also assumed you are US or somewhere non-uk so have used (hot, neutral and ground).
I have just drawn one power cable as the others are just repeats.
If you want me to clarify or draw a different way I will.
Here is the diagram:

Thanks JAMA
