Ok, done with the reset, twice.
On iOS 5 (I can't test older versions) the Reset all Settings requires you that you really really mean it with a couple of dialog boxes, then goes through a couple of progress bars. Once it is done it takes you through some basic setup for language, location, network, and a couple other things.
When that is over it will ask you if you want to restore like new or restore from a backup (iCloud or iTunes). This is kind of scary because it seems to say you are going to replace everything on the iPad if you go new. You are not. Even your account settings for mail, calendars, etc will not be bothered, let alone your apps an data.
That said, the first time I did it I chose to restore my settings from an iCloud backup. When it finished I had to start the iPad again. I got a couple dialogs about restoring apps, and a warning that some apps could not be restored. I have to assume this meant some of the settings in the apps, since all apps are present and accounted for. It did take several minutes for the whole thing to complete.
The second time I went with the new iPad option. This was fast and clean. The email accounts survived, but most other settings defaulted. The most obvious is that I'm back to the raindrop background.
The second is what I recommend you try, assuming the Google search suggested by dbr_52 doesn't turn up something better.
You will need to go through your Settings in detail to get things back to exactly how you wanted them.
