The best way to set that iPad up for your use is to restore it. You'll end up restoring to the newest iOS version (5), but at least it'll start out all fresh and new. Which, IMNSHO, was how the original owner should have given it to you (since you can't use their apps, passwords, etc.).
Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
