Uh no. Please go back and read the manga.
Let's look at Sakura's actual manga canon evolution.
Sakura fangirls over Sasuke in most of part 1. (oh and by the way- Hinata fangirls over Naruto, and Hinata still did clear up to the end of Pain invasion- way into part 2 of the manga, and even now it's still pretty much the same, except possibly she might be moving on from the romantic fantasy- it's a bit unclear if she has even that.) The crush is born out of seeing something in the boy that she wishes she could be- (both for Sakura and Hinata).
Sakura attempts to communicate with her crush, and is open with her support for him, also showing open tenderness toward him when he is hurt (and she does on a essentially equal level as well with Naruto even though her romantic feelings for Naruto in part 1 are semiconscious and confuse her a bit until the end of part 1). Sakura's fangirling of Sasuke begins to painfully slip away in the Forest of Death and ends for good when she makes her confession. We see the results of Sakura's heartbreak and final release of her fangirl fantasy when she begs Naruto to help her- we already see she's acknowledging Naruto is the only one who ever had any kind of bond to Sasuke.
By the time she sees Naruto in the hospital in part 1, she asks Naruto to give on his promise to her to bring Sasuke back, and when he refuses, her next words make it certain she has said goodbye to her fangirl crush on Sasuke forever and has completely accepted that- it's all about valuing Naruto's bond to Sasuke. That bond she knows was real, that image of Sasuke was real, and she wants to save that Sasuke- for Naruto. (She says it then, and says it each time saving Sasuke comes up in part 2. It's that Sasuke she sees when her hand shakes and she can't kill him, not the fangirl image.) Note how when she speaks to Sasuke she makes absolutely no reference to any feelings toward him whatsoever, she doesn't ever smile, blush or flirt either time in part 2 when she encounters Sasuke. Sakura has always been a girl who shows her romantic feelings- which is why even in part 1 when her feelings for Naruto were semiconscious and confused, she still blushed with her attraction to him and she had a special smile just for Naruto, and from the beginning of part 2 she outright flirts with Naruto.
She absolutely has no illusions about Sasuke at all now. It makes her feel sick and ashamed that she may harbor remnants of feelings for Sasuke- that's the complete opposite of fangirling. She sees the monster Sasuke really is and it makes her feel sick that she could ever have fangirled over him, she feels like that means something is wrong with her.
And as for you last comment, she didn't know his goals- if you read the manga you'll see he barely ever even uttered one word to anyone outside of his family- and that was before his family was killed, this was even more true afterward. He told no one his goals until that moment, if you notice even Naruto was surprised, and he was the only person in their class who had had any kind of real interaction with before they graduated.
And look at Hinata- she followed Naruto all the time but didn't understand him at all nor did she ever do to show him any kindness. She was chasing an illusion every bit as much as the Sasuke fangirls were with Sasuke. Hinata just lucked out that the boy she crushed on found a bond with others (and Sakura was a crucial one of those) who kept him from going into the darkness...
Ciardha, right againwith another batch of awesome!
Anyhow, yeah, in the long run, I can imagine Sakura will eventually come to find out Naruto was the one who was posing as Sasuke, and the hurtful things she said yet she sees the real Naruto now so I doubt it'll be too dramatic or her, given that whenever she's thought of Naruto, especially in Part 2/Shippuden, that she feels happy, hopeful, like anything is possible. And we've seen she's shown a lot of faith in him, but willing to help when push comes to shove. If she knew what was going on with Pain pinning Naruto down, I bet she would have ben done there faster than Hinata was. Given she didn't want to intervene I'm sure because she was tending to Tsunade and others hurt by the Shinra Tensei as well as her having faith Naruto would win.
That's the one thin I've seen with Hinata too, Ciardha; she only saw what she wanted to see of Naruto and never got to see his true strength comingnot from his being able to stand up again and never give up, but also his ability to reach out to others and befriend them due to his true nature being one of a kind boy who seeks companionship from others who didn't know or see he truly wasn't a monster.
Hinata shows that a bit in Shippuden when she waches Naruto get kicked by Tobi and doesn't keep her eyes on him. It shows she has a lack of faith even if she loves him. Just as when she didn't want Naruto to keep fighting when he was nailed by Neji's 8 Trigrams 64 Palms. The thing is, Hinata's admired Naruto from
AFAR and doesn't know the real him for what he truly is. I like to think part of her still sees him as the proud failure because she WANTS to see that about him.
Like you said, Sakura changed a lot after the hospital scene in Part 1 as well as her training with Tsunade; she seems like she doesn't wish to save Sasuke for herself, but to save him for Naruto's sake, even going as far as to rid the burden Naruto's had to carry because of her feelings for him nd feeling she hurt him worse than the other villagers in the Leaf did by seeing him as a monster.
It's from being around him and seeing how he really was that Sakura got to see that she was horribly wrong about how she perceived Naruto just like everyone else. Hinata, on the other hand, hasn't gotten over that yet, and until she does, she may not ever fully understand who Naruto Uzumaki really is.
