I'm no professional but I think you can either do:
1. Gaara, Temari and Naruto with talents 1133 or 2. Gaara, Haku and Naruto with talents 2122

The difference between the team that you have and what I suggested is mainly that your team has Sakura that can heal the team. If you want to use that team, then I would maybe switch the wind dance talent with flower guard, since Gaara generates a shield for himself each round, and the wm clones would get a boost from the flower guard.
