It sounds like you have the basic idea of what to do, remember to treat your filter media in exactly the same way as you do the fish, bag it in water and make sure it stays warm and when you bag the fish keep it at 1/3 water 2/3 air in the bags to ensure the water stays oxygenated.
The only other thing is stay calm and dont rush or panic, keep a level head and moving tanks and fish is a doddle, last month i moved 13 tanks and over 100 fish and only lost one small tetra through-out the move.
