There are probably five different ways to get into your iPad without having your passcode but some of them involve resetting the entire iPad would you lose everything or going online using your Apple ID and resetting it from iTunes. Easiest way to do is make an appointment at the Apple Genius Bar let them do it in 5 minutes
Not really a question we can answer online. You can take your iPad in and see what options they will give you. Alot of time they have to reset your device entirely and restore it to a back up. That's assuming you don't remember the passcode. If you remember the code make sure your device is charged and locate the power button to turn it on. Put your code when prompted.
