This one tool google offers, it is called like Google "AJAX API Wizards Video Bar" something along those lines but it makes a Video bar for you which is really helpful.
I find Google Analytics extremely useful, unlike AWstats it is better for geolocating your users and determining which is spam and which to target towards.
I too use Google Analytics and its one of the best website analytic tool available....there may be others but I dont like them...another tool I use is the Google Adwords Keyword tool which is an awesome to check which keyword gets how many search hits and gives u an idea about how popular your niche is gonna be!!
