I'd suggest goals and segmentation are two of the most interesting things you should look into. Goals allow you to track things like conversions. E.g. how many people filled out my contact form, how many people purchased something, etc. Segmentation allows you to see how groups of users are behaving. E.g. are my first time visitors looking at as many pages as my returning visitors?
