My New Kindle Fire

So I recently got a Kindle Fire as a gift.  I love it!  BUT - I can't update my blog (at least I haven't found a way to) and I can't play Candy Crush (i'm an addict!).  I'm sure there's more that I haven't figured out yet - I just haven't gone through everything.  Anyone who has one - any suggestions?  Summer reading?  Apps?
