No, they were not brought back at full power. The difference in their powers from life to Edo Tensei was shown with Madara as an example, he easily broke Hashirama's jutsu once he came back to life. All the Edo Tensei's shown were all weaker in general than they were in real life. In actuality, if Itachi and Nagato were revived back to life in healthy fully able bodies with their eyes restored to prime such as full eyesight for Itachi, and both Rinnegan for Nagato, then the war would not have lasted long.. shoot if all 4 Hokages were revived back to life too then Naruto and Sasuke would of just been mediocre looking in the war.
