If you updated over the air (in Settings - General - Software Update), connect your iPad to iTunes, back it up and restore it. This will install a fresh version of the software (it's 9.0.1 now) on your device, and should help getting rid of the problems you're facing now.
After updating/restoring, reset your iPad. I've described the procedure in my reply to your first post, here's it again, just in case:
Press and hold Home and Power button until you see the Apple logo. Release both and let your device power up on it's own.
Hope that helps.
