Statistics in WordPress

Hi

I moved to wordpress this week from blogger and I am wondering about quick stats. Is this the same as wp statistics? I activated wp statistics and now I see something called quick stats under my dashboard. Is that wp statistics?

Also, how do I turn of my own visits to my site so they are not viewved among the statistic? Or is this already enabled from the start?

I also wonder where I can see what sites people are coming from when they are going to my website.
Now I see their IP, country and search engine. But I cannot find a window that says which sites they are coming from directly to my blog. In blogger I could always see what site a particular visitor was coming from to read my blog.
