But i wanted to ask, would this wire be good to wire it all together? http://uk.farnell.com/pro-power/rrp-t-104-pk2/wire-tinned-copper-1-0-25mm-pk2/dp/1307796

Good luck on the assembly.

Shaky cam = bad. Try changing your sensitivity to 1 instead of 3 for all your axes. Also you have to adjust your "model position" under the model tab. You have to tell freetrack where the pivot point on your setup is relative to your head. I put Horizontal -101mm, that's to the right because my led assembly is to the right of my head. You might also want to fiddle with smoothing as it makes your movement less jerky. Someone might want to sticky this.
