Nope, just plant them in the substrate and they will grow new roots.
Some float plants to encourage root growth. I personally have not had the best success with that method (stems start to melt and no real root growth IME).
I just plant them straight away. Some remove any leaves that would become buried in the substrate. Some others also leave those leaves on to act as an anchor. I've done both and it seems leaving the leaves didn't cause any negative effect (those leaves would melt, but them helping keep it buried to establish roots was nice. And growth didn't seem stunted while those leaves melted).
If it has dead leaves, it may help to remove the badly damaged leaves (the plant would waste energy and growth time, trying to repair those unrepairable damaged leaves).
Other than that, nothing too it.
