Second, if you are back on 3.2.2, you probably need to get up to the latest version which is 5.1.1. You will be in for a world of pain trying to live with such an outdated version of IOS now.
You should follow ALL the instructions in the first post here exactly as they are written. This is a failsafe method, and unless your iPad has damaged hardware, it will work (the fact you are getting a 3194 error tells me you are not following the guide).
Once you are back on version 5.1.1 you can use Absinthe to re-jailbreak if necessary.
I would not recommend trying to use a back up from your 3.2.2 device. It is far too old now and too muck will have changed between 3.2 and 5.1 for that backup to be reliable. You will need to set the device up as a new device and sync your files, apps, media, etc. back from iTunes manually.
Hope that helps.
