Well, the Sweetie Belle Approved folder'd be a good start. Maybe Silent Belle's Picks while you're at it...

I'm cheating a bit with some of these, but you'll probably enjoy 'em anyway.

I can't recall the name right now, but there's a very good crossover with Sweetie Belle in Dreamland aka the Kirby franchise.

Dear Sweetie Belle (Technically, it's a Rarity story. But it's the beginning of series involving the CMCs. The three stories that are the letters are the beginning of an even larger story.)
Sweetie Bot - A Heart's Warming Tale and its sequel, Sweetie - The Magical Little Bot and it's Past Sins crossover, Artificial Daughter's Distress (The grammar can be a little jarring, but that's primarily because English is not the author's native language. But it's a great couple of stories based on the YouTube music video "Destabilized".)
Undead Robot Bug Crusaders and its sequel, Undead Robot Bug Crusaders: Unusual Lives
Three Wishes: The Cutie Mark Crusaders Before They Changed The World and its sequel, Three Wishes: The Hole In The Sun
The Sweetie Chronicles: Fragments

I'm also in the making of a story that takes place after the royal wedding. After the Changeling battle and the love wave, Rarity and Sweetie Belle are revealed to be Changelings. It's far from ready to be posted yet (in my opinion anyway). But here's the description:

When Rarity was invited to the wedding of Princess Mi Amore Cadenza and Shining Armor to design the wedding dress for the bride, and later to be a bridesmaid, she was absolutely ecstatic! But when Queen Chrysalis chose to crash the wedding, a deep dark secret is revealed about Rarity… a secret she hoped would never be revealed.

When Sweetie Belle was invited to the wedding of Princess Mi Amore Cadenza and Shining Armor along with her fellow Cutie Mark Crusaders to be flower girls, she was absolutely excited! But when the bride is revealed to be a monster in disguise, a deep dark secret is revealed about Sweetie Belle… a secret she didn’t even know she was keeping.

How will the Element bearers react to their friend’s secret?… How will the CMCs react to their friend’s secret?… And now that their secrets are revealed, who will protect them?

Friendships and familial bonds will be tested as a divide is created from the confusion.
