I have a similar setup to you, except that my server runs Linux. I've never installed Squeezecenter on a Windows machine, but I guess that it will ask you for the path to the music files somewhere. As the music is in the same box as Squeezecenter, you just need to specify the path in the usual way, eg

c:\stuff\music

The http://<your_server_name>:9000 is what you use to point a web browser on any computer in your house to Squeezecenter.

As for converting to mp3, there are many ways to do this. I use another piece of free software called foobar2000 - http://www.foobar2000.org/

Foobar2000 utilises a free utility called LAME to convert the FLACs to mp3. - http://lame.sourceforge.net/
