somewhere in the not-too distant past, I did the following:

you can edit the port setting in
/etc/zopeX/INSTANCENAME/zope.conf
where X is the zope version you're using and INSTANCENAME the name of
the instance.

If you install a package like plone-site, it should ask you on which
port you want to run Zope. The more common way is to run apache on port
80 and to use proxy rewrites. This allows you to add ssl wasily or to
run more than one zope instance behind port 80 (if you need this for
some reason, like testing).
http://wiki.zope.org/zope2/ZopeAndApache looks like a good tutorial on that.

Cheers,

Bernd
