Q: iPad help

You are going to need that AppleId password one way or the other: If you forgot your Apple ID password - Apple Support

If it's disabled you will need to reset it back to factory defaults - recovery mode : If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

To reset the iTunes account's password : http://iforgot.apple.com

If you know the email associated with the iPad, and you know the email address and email password, you can reset your apple password then login to your email and change your password.

If the iPad is disabled it doesn't matter whether or not you know its passcode, you will have to reset the iPad back to factory defaults
