Well, I think since Kabuto can heal, I suppose having a healer would be good for the team against Kabuto, just so you know ya know, you don't get injured and die?
Tsunade would be ideal. Plus, she's quite strong in Taijutsu, though we do not know whether she can even match SM style.
A Dojutsu user, Sharingan user, would be useful. They can track Kabuto, and thus making people like Kakashi a great asset.
Given that the terrain is in a cave, earth techniques experts should be able to showcase their expertise fully in here. Probably a Tsuchikage or Kitsuchi. I think Dust Release could be useful as well.
As for the last one, I have no idea. Other than Darui, not many use jutsus that can hit multiple enemies?
