There are others much more knowledgeable than I, but I would suggest:

in the global section, you add "encrypt passwords = yes". I also think you
need to specify a password server.

for the public (non-protected) share, you might want to add "public = yes" and
"writable = yes". For the private (non-protected) share, I'd add "valid
users = jdoe joeblowjr etc" and "public = no" and "writable = yes".

Those are things I can think of off-the-bat. The real gurus will probably be
able to help you with the availability issue.
