It does not require to re-enter the WAP/WEP.. code. It is stored. I do turn it off/on many times without requiring the code. It does require to enter a code when you are signing in another protected wifi spot.
You shouldn't need to re-enter, but some people are experiencing issues with wifi disconnecting and requiring you to re-enter you wep key. Its only happened to me once, but its a pain having to retype that thing. Hopefully, it gets fixed in the update coming. Supposedly you can fix it by changing to WPA instead of WEP on your router. Of course, this assumes you are connecting you your own router and not a public hotspot or such.
If you don't know how to look at the above links on your iPad, use your PC/Mac to view. Learn some basics about your iPad, it will make things a lot easier for you....
The WiFi doesn't drain that much of the battery when idle so why would you really want to shut it off anyways? On the other hand 3G is a different story.
