If you make Sakura stronger, you should also make Ino stronger and not follow Sakura's medic path.
Let Sakura learn Kakashi's demonic hell viewing technique? With cherry blossoms...
For chapter 1....
Naruto plans to play a prank on the Uchiha Military Police.
Sakura's sneaking around the Uchiha Compound entrance because she has a crush on Sasuke and wants to see how he lives, etc.
They bump into each other and Sakura scolds Naruto for planning to prank Sasuke but asks him how they're going to get inside.
Naruto teaches Sakura a few of his tricks on evading ANBU and they sneak into the compound and explore.
Sakura and Naruto see Itachi carrying Sasuke home.
Then they leave.
Sasuke's internally fond of Naruto b/c he's the only boy who doesn't try to suck up to Sasuke as an Uchiha heir or for his skills.
Sakura simply hangs around Naruto.

later
Naruto fails the graduation exam and Sakura grabs Sasuke's hand and goes to the Hokage Tower, planning to convince the Hokage that Naruto is stronger than half the kids in class and that's why he shouldn't be held back because of 1 E-rank jutsu.
Mizuki gets to Naruto.
Hokage uses his crystal ball to watch Naruto find out about the Kyuubi, and at that moment, Sakura and Sasuke burst in the door and see what happens in the Crystal Ball.
Naturally they find out the truth and (reluctantly) go comfort Naruto over it.
I always felt keeping the Kyuubi secret to himself always bothered him, but he covers it up with fake cheer. Maybe it's better for Naruto's sake, to share his secret a little bit.
Just an idea ^^
