i moved two 55 gallons in the fall of 2009. lots of fish including some big guys (including an oscar who was about 8 inches at the time).
smaller fish, snails, shrimp, and all my plants went into a 20 gallon rubbermaid, filled about half full, with the lid on. bigger fish each got their own 2 gallon bucket, with lid! canister filters i unhooked, left full of water, and hooked back up as is at the new place. hob filters got their media tossed into a 5 gallon bucket filled with tank water, and media was put back in hobs as is with no rinsing. tanks got pretty much drained completely, with maybe an inch of water left at most. substrate and large decor (wood, etc) was left in the tanks. missed a few green shrimp when catching all the fish/critters and they survived being transported in an inch of water, open tank, open bed truck, on a cold, dreary, and slightly rainy day, lol. the rubbermaid and buckets of fish were transported in the truck's cab, without any air conditioning running.
for your situation, i'd just do a rubbermaid tub for all your fish (and plants if you have any). drain the tank, don't bother saving any water (setting the tank back up will be like a huge water change for your fish). follow the details in my above paragraph for filter/filter media moving.
good luck with the move!
