GASP!!!!! That many fish?? Wow!
Jason, pretty much what I said on the first page. Some dry food once a day, making sure it all gets eaten. Mysis once a week as a treat. Best way to clean the fluval is FW with bleach. Then post it for sale to someone with a fish only tank. Cannisters don't belong on reefs. Live rock is there to perform nitrification, not cannisters. They are competing with each other, and your rock will suffer. To remove it, take out half the media this water change, and then take the whole filter out at your next water change. This will let your rock build bacterial populations to compensate for the loss of the cannister.
And while the fish load is on the high side, it is easily manageable. I wouldn't worry about keeping them all until you get the 180 going.
