My wife's new iPad needs help

I just bought my wife an iPad for Christmas.
She is NOT a techy, but reads her email, checks Facebook occasionally, stores and shares lots of pictures with friiends & family, and does google stuff and recipes. She didn't want an laptop, so I thought this would be good for home / WiFi use.
(I'll also use it too, but it's mainly for her)

What Apps do you recommend and is there any setup / configs I should do?
Anything else? Any other uses I haven't thought of that a casual user might enjoy? I wanted to have it setup for her for Christmas.

btw, I have an iPhone and she likes it, but we don't plan to use this as a cell phone.

iTunes, Contacts, Email, Calendar, Facebook, Google Earth, Kindle, QuickOffice Pro, Filterstorm, AVPlayerHD, SVT Software (checkbook), Jamie's Recipes, Garageband, Angry Birds, Whatsapp ...
