When you get the warning, go ahead and hit cancle. Now got to your iPad where it is listed under devices, right click on it, and choose Transfer Purchases. This should transfer your apps to iTunes. It might duplicate music and movies. I'm not certain.
Or if you choose to Erace and Sycn, make a list of your apps first so you know which ones to download again. A quick way to do this is just use screen captures and mail them to yourself.
