You should put the name of your distro in your user profile. Many distro's have a wizard to help set up a samba server. Also, look for a samba-doc package. There may be a book supplied called "Samba 3 by Example" that has several sample configurations you can base yours on.
I you also know very little about how networks work, look in the www.tldp.org
website for the Network Administrator's Guide (nag).
