The easiest and best way for you (you'll get updates through signed packages, etc) is probably to install via the Ubuntu Software Center.
Though it can be difficult to download and run random software from the internet, I have to say, most Linux distributions have got the software distribution challenge through their package managers right compared to OSX and Windows. First thing I do on an OSX machine is install homebrew which helps a little.
