Step 3: Interface the timer to the LED driver

Next, interface your 555 timer circuit to the Buck Puck LED driver. This is easy. Just put a jumper wire from pin 3 of the 555 to the control pin of the Buck Puck.
I would wait to attach the Luxeon V to the driver yet. If you power it up, and it's not heatsinked, it can go into thermal runaway and melt itself down.

Note that the ref pin is not used.

im at a loss here. Alot of steps seemed to have been skimmed over or skipped completely.

By heatsinked are you referring to the Buck Puck LED Driver or the Luxeon V?
