you should clean the gravel by rinseing it with cold-room temp water, if you use hot water you will kill of the bacteria that has formed - this will help with the cycling process.
you can use undergravel filters - I do and I like them, but some on this board don't like them.
as for setting up the large tank look here

you don't need to add old water to your new tank IMO but it will not harm the fish if you do.
as for treating the ill piranha - what is wrong with it?
but you will find it easyer to treat in a smaller tank because it will use less medication, but when re-introducing it you should re-arange the tank decorations to reduce aggression
oh, and what Gargoyle said
