I'd also recommend jumping head first and start looking at analytic solutions while going through blogs and books. I'm assuming you have a website already that you want to start crunching data from — beyond the obvious analytics.google.com, I'd recommend:

http://www.clicktale.com/ (watch actual browsing behavior/generates heatmaps)

http://www.crazyegg.com/ (another heatmap generator)

http://ethnio.com/ (less about analytics but usability is good too — this helps recruit users for usability testing straight from your website).

http://www.kampyle.com/ (get feedback from your users from a little widget).

http://www.kissmetrics.com/ (track and optimize conversion funnels)

http://mixpanel.com/ (more of a general analytics solution)

You don't have to use all of these solutions, but start playing around with some and pulling in data.
