I am doing a similar thread in this forum with a lot of the same equipment. Since you've ordered your equipment already I think I'll see how yours turns out before I buy my supplies in case I want to alter what I'm planning on now.
Have you tried looking at http://www.heatsinkusa.com/
for a heat sink you can connect your driver and LEDs to? Originally I was going to buy one from them, but I was able to find heat sinks at www.rapidled.com
where I will be ordering my equipment from. Keep us updated! I'll definitely be following your thread
