All data on the iPad is automatically hardware-encrypted, so perform-
ing a remote wipe doesn't actually remove any data; it changes the
encryption key, leaving the encrypted data useless. As a result, wiping
is fast, taking only a minute and a half.
If the iPad does turn up after a remote wipe, connect it to your
computer and restore everything from the last backup.
Speaking of the iPad's backup, you can perform remote wipes all day and
it won't matter if the computer you sync with was stolen along with the
iPad. You can get some measure of relief if you also encrypt the iPad data
backup that's stored on the computer's hard disk.
In iTunes with the iPad selected in the sidebar, go to the Summary pane
and enable the Encrypt iPad backup option.
