Hey Dom!
Glad you got FW up and running!
I generally look at the following items in FW...
1st)
General TrafficI usually check "Unique Visitors" and then head to "Traffic Statistics" I then take a look at "One-time visitors" and "Repeat visitors" I like to see how many users are coming back
2nd)
Server Preview - PagesI then take a look at what pages the users are entering the site on and what pages the users are exiting on. This is a good way to tell what your hot and cold sections are.
3rd)
Marketing Preview: Time OnlineHow much time are the users spending on the site, I'm never satisfied with the numbers lol

It makes me turn up the heat and build better content or create new interesting sections.
4th)
Referrals - Preview: Referral Sites and Search Terms I'm sometimes pleasantly surprised by this chart, great way to see if your link building is paying off! and of course...Search Terms!
I usually open up marketleap.com and check rankings using the search terms people hit the site with.
5th)
Systems - RobotsTo make sure the spiders are hitting the site
Take Care!
