Welcome to iPadForums!
Maybe your internet connection is a bit slow, so you just have to wait a bit for the icons to load.
If they don't appear, no matter how much time you give it to load, try force closing Safari:
Double tap the Home button to show the App Switcher, showing the apps you've used, and slide the thumbnail below the Safari app icon towards the top of the screen.
If your bookmarks still don't appear, force start your iPad:
Press and hold Home and Power button simultaneously, until the Apple logo appears. As soon as it's visible, let go of both. Your iPad will power up on it's own.
