As those are hydraulic you'll only need shift cables. Shift cables are always compressionless. I'd imagine those would come with some? (I couldn't be bothered to read the product desc.).
No point, standard Shimano stuff work perfectly well, as long it's trimmed nicely, not too long/short, etc. it will shift great.
It's only with cable operated disc calipers is where compressionless housing can make a difference (as well with mini-v and occasionally v brake with road levers).
