Welcome to the forums! For the dimmer packs, whatever address you set it to (129 for your example) tells you all the address for each light. light one will be 129 and light 2 will be 130, 4 - 131, 5 - 132. so just use the faders (channels 129 - 132) to turn on the par cans. Make Sense?
For the ADJ Accu Spot 250 II's, I'm not entirely sure how to do what your thinking but what I would suggest is to set some scenes and just recall your scenes. Set the first light to the left of the runway and the second light to the right and save that as a scene. then just recall the scene during the show.
Hope this helps!!!
P.S. you may not get very many replies until everyone gets back in the office!
