Don't call yourself lame, dude. Don't be so hard on yourself; everyone makes mistakes now and again. The problem is that you jailbroke the iPad and then you tried to fiddle with it. The problem has arisen by the fact that you are unfamiliar with what a jailbreak is and have tried to muck about with the iPad instead of following the guides and reading up online. Unfortunately you have no-one or nothing to blame except yourself in this instance. All the jailbreaking guides out there warn you that you can damage your device if you don't know what you are doing. It's a steep learning curve and I think you have been guilty of a little impatience.
Have you been following the advice of people in this thread? Have you disabled cloud backups in iTunes and put your device in DFU mode via the link in rdiddy_25's signature -

DFU has a greater chance of assisting you restoring the device now as I think you have potentially deleted some aspects of the operating system. Go into DFU (link above) and connect the iPad to iTunes.
If you do manage to get your device back to factory, I would strongly suggest you don't try jailbreaking again.
