Help needed with Google Analytics

Hi -

I was wondering if someone out there would be willing to run through some basic Google Analytics reporting with me, specifically with reporting on social media referrals. I understand the basics, but am now having to take things to a new, deeper level of reporting, tracking e-commerce conversions from an e-commerce client. 

Even a pointer to some good online resources would help - there are so many blogs out there it's hard to know where to start!

Many thanks

Emma
