hmmm.. sorry that didn't help
It's ok, everyone feels like this when they start using linux gradually you'll get more of an understanding
Don't let config files scare you, they are usually well commented (lines starting with #) and should help you out.
Generally, most config files are stored under the /etc directory (for samba it should be under /etc/samba/smb.conf). To find out the where the config files are stored and which one to edit, try the man pages (man samba) Down the bottom are the files that samba uses and the config files are generally listed. The whereis samba command should also tell you where it is stored.
Hope that helps you out
There is a man page for smb.conf too, and I think there is a samba howto on tldp.org (the linux documentation project) Good luck!
