Easiest way to look at the windows files is from within Konqueror, put smb://machine_name/ in as the address.
Samba is pretty easy to configure, install the RPMs, then you can set up shared by editing /etc/samba/smb.conf and restarting smb and nmb (which might be alised as just "samba" in your /etc/init.d/ directory - /etc/init.d/samba restart).
http://david.us-lot.org/linux-config.php has an example smb.conf file.
