Hello ccrjon,
Thank you for providing so much detail about the issue you are experiencing with PDFs in Safari after upgrading to iOS 7.
The first thing I recommend is quitting and relaunching the applications on your iPad:
- Double-click the Home button.
- Swipe left or right until you have located the app you wish to close.
- Swipe the app up to close it.

If you are still seeing the same issue after quitting and relaunching Safari, I recommend restarting your iPad and then resetting if it's still not working:
Restarting your device
- Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
- Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

If the issue persists, the last thing I recommend is backing up and restoring your iPad:
