About Sasuke giving the thank you to Sakura, he was honestly thankful to her but this was kind of a last act of kindness before his corruption by Orochimaru.
It was like when Sasuke stepped out of the village, the further he got the more he lost his former self. Sasuke knew that if he wanted revenge, he have to get his hands dirty so before anything happened he gave one last act of kindness while he still his good sense of morale, he did not want his teammates to get involved because he felt Itachi was his duty, so before he left the village, it was an act to ensure they would not get involved.
The way Sasuke ran from the village reminds me of way back in the teen titans show when Raven found out she was supposed to bring the end of the world, she tried everything to avert it but it was not enough, her friends tried to stop and protect her from it but in the end she gave in, however before the evil act was commited, she encased them in a protective shield so they would survive the end of the world before they actually had the chance to fix and restore it.
What I mean is, Sasuke still in the village when he faced Sakura and like Naruto as well, he did not want them to get involved as he left and did not want them to chase him, because he was set on killing Itachi.
He wanted Sakura and Naruto to be left behind for these reasons:
-It was his business
-He did not want them to get in the way
-He did not want them to get hurt for his goal
However he left Naruto alive in the VoTE because he did not want to obtain power in the same way Itachi did, the MS was obtainable by killing your best friend. He left Naruto alive so as not to follow Itachi (as he thought back then). After Orochimaru corrupted him, he merely wanted them to leave him alone, only threatening to harm or even kill them if they interfered. When Itachi's truth was revealed then he was set on killing his former teammates and classmates, his memories got twisted and made him think that the peace they enjoyed was at the cost of using Itachi. Obviously Sasuke entered emo rage mode at this point and tried to kill Naruto, Sakura, and Kakashi all in one go in this short arc. When Sasuke meets up with team 7 again, either there has to be some caution with them when they first meet given the last situation or Sasuke better still be harboring some resientment to the village for using Itachi like Naruto did for the past hate he had towards the villagers even though they trusted and respected him for beating pain. Only naruto managed to kill his hate by accepting himself and trusting in others who trusted in him.
Now if anything though this still means Sasuke never saw Naruto or Sakura as anything more than friends. He saw Naruto as a rival and friend and Sakura merely as a comrade/friend nothing more.
It was more of him trying to sever the bonds he had made for power in my opinion and here's why. Up until he finally defeats Naruto in the VOTE, Sasuke is trying to gain power because of what Itachi told him. The reason he says thank you is to sever his bond with Sakura. However, because Naruto fights him and manages to scratch his forehead, even giving in to the fox to save him to which Sasuke asks "why are you doing this for me?", Sasuke fails to sever the bond between himself and Naruto. That was the whole point of the VOTE fight, that Naruto managed to preserve the bond between himself and Sasuke. This led to several later events which prove this. First, because of the bond, Sasuke cannot bring himself to kill an unconscious Naruto and vows to not follow in Itachi's footsteps. Then in the first Team 7 reunion, he specifically says, "I managed to sever all of my bonds ."

http://www.onemanga....o_manga/307/12/Then of course we have the Land of Iron reunion where he almost kills Sakura, laughs at Kakashi, but then stops and tells off Madara to listen to Naruto.
As for Sasuke acknowledging Naruto, bottom line is that other characters can say whatever. But only Sasuke can speak for himself. And he clearly stated that he considers Naruto his equal.
