Would I have to cycle a new tank if I already have a tank?

Assuming you're not adding more rock or livestock in the process I don't see why you'd have a cycle.

WOuld be easy enough, I woudln't recommend reusing the sandbed though.

Use as much as the old water as possible, and maybe to help stabalize it, use seachem's stability.
