I'm in the same boat my first ipad - Ipad 3 32gb wifi.
I highly recommend anything by donut games and llamasoft - I have pretty much downloaded there catalogue of games
A little app called flip board is also brill it creates a personal daily magazine for you from your interests - really cool.
The Iplayer app works really well - I watched the Wales v France rugby match on it yesterday (well done Wales (8 ).
Another cool alternate app store app is called App Shopper and lets you sort by "free" price catagories etc - which I found very hand and also lets you know of any daily deals
I had a hard time getting my favourites from chrome to safari - in the end I had to export them from Chrome to IE on my laptop to get Itunes synch to work :/
Loving the Ipad so far though - so many free/cheap apps but all seem to be high quality
