The first recommendation that I will give you is DON'T update the iPad if you are running 4.3.3, I'm not telling you to Jailbreak now but if you will like to do it after you read and feel more conformable then your only choice will be to be running 4.3.3 and going to jailbrekame.com using the safari in the iPad

Read, read and read... this forum has a lot of info and pretty much every question you have is been answer, however is you don't see the answer there then ask/post.
